Glücksburg Castle

Like a white cube, Glücksburg Castle seems to rise straight out of the water. The Renaissance castle on the Flensburg Fjord stands on a 2.5-metre granite base in a pond that once swallowed an entire monastery. It is the ancestral seat of the House of Glücksburg, whose descendants still sit on the Danish and Norwegian thrones. Germany's northernmost castle is now a museum and concert venue.

History

Cistercian monks founded the Rüde monastery here around 1210. After the Reformation the land passed to Duke John the Younger, brother of the Danish king. On 21 December 1582 he signed the contract with builder Nikolaus Karies, who demolished the monastery, reused its bricks and dammed the site into a pond. The duke budgeted 6,000 Lübeck marks, then worth about 1,200 cattle, and the castle was finished in 1587.

From 1622 it was the seat of a ducal line. Danish King Frederick VII died here in 1863; his successor Christian IX, of the Glücksburg line, married his children into Europe's royal houses and became known as the "father-in-law of Europe". One son became King George I of Greece, a grandson King Haakon VII of Norway. Albert Speer was arrested at the castle in May 1945. A family foundation has owned and opened it to the public since 1922.

What to see

• The building: three joined houses forming a square of almost 30 metres, with four octagonal corner towers.
• Red Hall: a 30-metre hall on the first floor with some of Schleswig-Holstein's earliest stucco work and paintings by Antoine Pesne, among others.
• Chapel: the only room set across the main axis.
• Finds from the pond: when it was drained in 1962, 1969 and 2005, the foundations of the monastery church came to light; some finds are on display.

The best photo is from the far side of the pond. Allow about two hours. The rose garden next door has over 500 historic roses but is privately run with separate admission.
