Glücksburg Today – The Legacy Lives On ## The Beginnings – Stone Age, Vikings and the Rudekloster The history of Glücksburg begins long before the castle and even long before Christianity. **In the Friedeholz forest south-west of Holnis, megalithic tombs from the Neolithic era still stand today** – silent witnesses to a settlement that reaches back at least 5,000 years. Stone Age people moved along the fjord, fishing, hunting and burying their dead in enormous granite blocks. The actual founding story begins in the year **1209**: Cistercian monks built a monastery on a small peninsula on the shore of the Flensburg Fjord – the **Kloster Rus Regis**, in Danish _Rudekloster_, in English the Monastery of Kings. The monks came from Sorø Monastery on Zealand, and their new house on the Angeln peninsula was to be both a bastion of faith and a centre of agriculture. The **ferry between Holnis and Brunsnæs** was no mere fishermen's path: it connected the Rudekloster to the church in Broager, which the monks had to cross to regularly. One of the oldest documented ferry routes in the fjord region, already recorded in the 13th century. #### Glücksburg in Numbers and Facts First traces of settlement Neolithic (~3000 BC) Rudekloster founded 1209 AD Castle built 1583–1587 Castle construction cost 6,000 Lübeck marks (≈ 1,200 cattle) Town charter granted 1900 First Kurhaus Sandwig 1872 Northernmost town in Germany Yes – geographically confirmed Holnis nature reserve 360 ha since 1993 ## The Castle – Duke Johann and 1,200 Cattle ![Glücksburg Castle — the white moated castle reflected in the castle lake](/assets/region-schloss-gluecksburg-960w-BgsXFK2J.webp) GLÜCKSBURG CASTLE · BUILT 1583–1587 In 1544, King Christian III of Denmark dissolved the Rudekloster during the Reformation and transferred the monastic estate to his brother, **Duke Johann the Younger** (1545–1622). This marks the decisive episode: a ducal builder with 23 children, a passion for architecture and the ambition to create a grand residence on the fjord. Shortly before Christmas Eve 1582, Johann signed a contract with the master builder **Nikolaus Karies**: **6,000 Lübeck marks** for the construction of a moated castle – roughly equivalent to the value of 1,200 cattle. The building material was around 800 years old; the castle itself was completed in just five years, between 1583 and 1587. What emerged was extraordinary for the region: a **square Renaissance castle measuring 30 × 30 metres**, erected on a 2.5-metre-high granite plinth above the castle lake, flanked by four octagonal corner towers. Listed in German heritage protection to this day, described in the Michelin Guide as a 'white castle by the sea'. > God grant fortune with peace – the motto of Johann the Younger above the entrance portal. The initial letters of the Latin version gave the castle – and thus the town – its name. > > Inscription above the entrance portal, Glücksburg Castle, 1587 The name _Glücksburg_ derives directly from the duke's motto: _Gott Gebe Glück mit Frieden_ (God Grant Fortune with Peace). Johann married twice – 14 children from his first marriage, 9 from the second – and was superbly connected: brother-in-law of the Elector of Saxony, recognised at the court of Emperor Maximilian II, brother of the Danish king. A particular treasure of the castle is the **richly coloured calfskin leather wall-hangings**, probably made in a Mechelen workshop around 1680, which can still be seen in the state rooms today. The castle interior is largely preserved in its original form – a stroke of historical fortune. ## The Dukes of Glücksburg – Five Generations After the death of Johann the Younger in 1622, the small duchy was divided among his sons. His second-youngest son **Philipp** received the castle and estates of Glücksburg, founding the elder line of the _House of Schleswig-Holstein-Sonderburg-Glücksburg_. For the next 150 years, the castle served as the seat of five generations of dukes. 1622 Philipp receives Glücksburg Castle, founding the elder ducal line 1663–1779 Four more generations of dukes inhabit the castle; the line dies out without heirs in 1779 1779–1824 The fief reverts to the Danish Crown; the widow of the last duke, Anna Carolina, uses it as her dower seat 1825 King Frederick VI transfers the fief, title and castle to Friedrich Wilhelm of the House of Holstein-Beck – founder of the younger Glücksburg line 1831 Friedrich Wilhelm's son Christian is called to Copenhagen – the future King Christian IX grows up here ## The Cradle of Europe – Christian IX and His Children In the history of Europe, no castle has exerted such a far-reaching dynastic influence as little Glücksburg on the Flensburg Fjord. The reason lies in one man: **Christian IX** (1818–1906), who was called to the Danish throne in 1863 after the childless death of King Frederick VII. > He was called the father-in-law of Europe – and he fully earned the title. There was scarcely a royal house of the late 19th century that was not connected to Glücksburg. #### The Children of Christian IX and Their Dynasties Princess Alexandra Married the future King Edward VII of England – grandmother of George V. Princess Dagmar Married the future Tsar Alexander III of Russia – mother of Nicholas II. Princess Thyra Married Duke Ernst August of Cumberland, last heir to the throne of Hanover. Prince Wilhelm Became George I, King of Greece. Grandson Carl Became Haakon VII, King of Norway. Today The House of Glücksburg still reigns in Denmark (since 1863) and Norway (since 1905). From Glücksburg, the throne rooms of England, Russia, Greece and Norway were filled. When you stand on the beach at Bockholm today and look out across the fjord, you are looking at the waters that once bound these family ties together. ## War, Prussia and the Family's Return 1864 brought the end of the long personal union between the Danish royal house and the Schleswig-Holstein duchies. During the **Second Schleswig War**, Glücksburg Castle served as quarters for Carl of Prussia, then as a field hospital and barracks. On 16 September 1868, King Wilhelm I of Prussia visited the castle personally to decide its future. The decision was merciful: Wilhelm returned the castle to the family. **In 1871, Duke Karl moved back into the castle** – a return that has kept the castle in family ownership to this day. 📍 The 1920 plebiscite, after the First World War, was the last great political turning point: Glücksburg voted to remain with Germany. Since 1863, kings from the House of Schleswig-Holstein-Sonderburg-Glücksburg have reigned over Denmark. ## The Seaside Resort – Steamers, Beach Chairs and Thomas Mann ![Glücksburg pier with festively set tables and the beach hotel in the background](/assets/region-seebruecke-gluecksburg-960w-hJTgbUvx.webp) GLÜCKSBURG PIER · SINCE 1872 In the 1830s, a different story began: bathing operations in the **Quellental**, the first tentative attempt to establish Glücksburg as a health resort. But the real rise to seaside resort status only began after the war, in the early 1870s. On **30 June 1872**, the first _Kurhaus_ opened on the beach at Sandwig. Six guest rooms, a year-round restaurant, a marquee for 500 guests. **Steamers docked at the pier every hour.** > The idyllic stretch of coast, with its pier and historic beach hotel, recalls the days when ladies still wore long dresses and took the steamer from Flensburg to Glücksburg for afternoon coffee. > > From a travel guide to the Flensburg Fjord In July 1873, the Kurhaus was expanded into the **Strandhotel Glücksburg** – 70 rooms, a large ballroom. It was the first building in Glücksburg to have a telephone connection. **From Flensburg to Glücksburg in one hour**, sitting comfortably on deck, the fjord on both sides. The Strandhotel attracted celebrities from across northern Germany. **Alfred Krupp** came for sailing. **Kaiser Wilhelm II** steered his yacht 'Hohenzollern' towards the landing stage in 1890. **Thomas Mann** and his publisher Samuel Fischer were guests in 1919. In **1885/86**, the Flensburg–Kappeln railway line was opened. **In 1900, Glücksburg was granted town charter**. The elegant seaside resort was now officially a town. 📍 Today's Strandhotel Glücksburg still stands on the same foundations as the Kurhaus of 1872. The pier below leads to the fjord steamer MS Viking – the same route as 150 years ago. ✦ ✦ ✦ ## Holnis – The Peninsula That Was Once an Island ![Aerial view of the Holnis peninsula — clifftop coast, green meadows and the Flensburg Fjord](/assets/region-holnis-luftbild-960w-BYsRI1c0.webp) HOLNIS PENINSULA · NATURE RESERVE SINCE 1993 Anyone walking on the Holnis peninsula today is treading on a landscape that is physically younger than the castle. It was only between **1920 and 1928** that the great lagoon was dyked and pumped dry – transforming the peninsula into solid land for good. The **Kleine Noor** tells the reverse story: **in 2002, it was reflooded** – creating a new 18-hectare body of water with saltwater influence. Today it is a rare saline biotope on the Baltic coast. ### Brickworks – the Economic Backbone For centuries, Holnis was a centre of the brick industry. At least three brickworks are documented: the **Holnis Brickworks** (from 1710), the **Schausende Brickworks** (from 1722) and a smaller one on the north shore. **The bricks for the castle itself are said to have come from Holnis and Bockholm.** ### The Nature Reserve and Germany's Northeasternmost Point Since **1993**, a 360-hectare section of Holnis has been a nature reserve. The northern tip of the peninsula is **Germany's northeasternmost point on the mainland**. At the tip stands the **Holnis Lighthouse** near Schausende – the northernmost lighthouse on the German Baltic coast. 📍 The Theodor-Fontane-Wanderweg trail runs across the Holnis peninsula. Those hiking the Fördesteig coastal trail pass through Holnis on Stage 5. ## Bockholm – Bricks, Cannons and the Coastal Trail Bockholm – in Danish _Bogholm_ – lies immediately south-east of the Holnis peninsula, one kilometre east of the castle. The street name _Berglyk_ means something like 'little hill' – and indeed, Bockholm sits on a gentle moraine ridge with unobstructed views across the fjord and towards Denmark. At the end of the _Alte Schulweg_ (Old School Road), right at the water's edge, stood the **Osterziegelhof Bockholm** – possibly one of the oldest brickworks sites in the entire region. At its peak, the entire coast had **over 70 brickworks**. During the **First Schleswig War of 1848**, Bockholm became a frontline: Danish troops landed at the southern bridge; from a hilltop in Bockholm – the _Johannisberg_ – a German battery fired on the ships. Two houses burned down. ### The Fördesteig – Bockholm as a Hiking Destination Today, Bockholm is a waypoint on the **Fördesteig**, the 95-kilometre coastal walking trail. **Stage 6 leads from Bockholm via Bockholmwik and the Siegum forest to Langballigau** – roughly 7 kilometres of nature trail directly along the cliff coast. 📍 Berglyk 8, Bockholm – the address of Villa Boreal – lies directly on the Fördesteig. The trail literally passes by the villa. ## Glücksburg Today – The Legacy Lives On Glücksburg Castle remains in the possession of the Dukes of Schleswig-Holstein-Glücksburg. Since 1922, a foundation has managed the ensemble; today it is a museum and year-round event venue – a stage for the Schleswig-Holstein Music Festival, a setting for concerts and civil wedding ceremonies. The town has just under 6,500 inhabitants and is the **northernmost town in Germany**. The Holnis peninsula, under nature protection since 1993, is today one of the most valuable biotopes on the Schleswig-Holstein Baltic coast. _Marina Holnis_ was supposed to become a hotel and apartment complex with a yacht harbour for 500 vessels – the plan failed. What remains is the silence. > God grant fortune with peace. The motto that a duke had carved above his gate over 400 years ago still describes this stretch of coast better than any modern marketing. When you look out from Berglyk 8 across the Flensburg Fjord, you are looking at the same coastline that once belonged to the Rudekloster, inspired dukes, accompanied kings' daughters and delighted holidaymakers in long skirts. The water is the same. The view towards Denmark is the same. The stillness of the early morning has not changed its character in 800 years.
