Viljandi castle was one of the strongest castles in Livonia. The construction was started 1224 under Teutonic Order in place of a former hillfort. The crusaders of Sword Brethren conquered the hill fort at the place of later main castle in 1223. A year later, construction of stone fortifications started. Viljandi was chosen as the high seat of the order.
The convent house, a typical form of castle of Teutonic Knights, was erected late 13th – early 14th century. In the following centuries the castle was extended and fortified further. It was badly damaged in the Polish-Swedish wars in early 17th century and not repaired any more. In 18th century, the ruins were used for quarrying stones for construction work in Viljandi.
The first excavations in the castle were performed in 1878–1879. In recent decades, these have turned to almost yearly events. Currently the ruins form a popular resort area just outside of central Viljandi. An open-air stage is located in the former central courtyard.
Lübeck Cathedral is a large brick-built Lutheran cathedral in Lübeck, Germany and part of the Lübeck UNESCO World Heritage Site. In 1173 Henry the Lion founded the cathedral to serve the Diocese of Lübeck, after the transfer in 1160 of the bishop's seat from Oldenburg in Holstein under bishop Gerold. The then Romanesque cathedral was completed around 1230, but between 1266 and 1335 it was converted into a Gothic-style building with side-aisles raised to the same height as the main aisle.
On the night of Palm Sunday (28–29 March) 1942 a Royal Air Force bombing raid destroyed a fifth of the town centre. Several bombs fell in the area around the church, causing the eastern vault of the quire to collapse and destroying the altar which dated from 1696. A fire from the neighbouring cathedral museum spread to the truss of the cathedral, and around noon on Palm Sunday the towers collapsed. An Arp Schnitger organ was lost in the flames. Nevertheless, a relatively large portion of the internal fittings was saved, including the cross and almost all of the medieval polyptychs. In 1946 a further collapse, of the gable of the north transept, destroyed the vestibule almost completely.
Reconstruction of the cathedral took several decades, as greater priority was given to the rebuilding of the Marienkirche. Work was completed only in 1982.
The cathedral is unique in that at 105 m, it is shorter than the tallest church in the city. This is the consequence of a power struggle between the church and the guilds.
The 17 m crucifix is the work of the Lübeck artist Bernt Notke. It was commissioned by the bishop of Lübeck, Albert II. Krummendiek, and erected in 1477. The carvings which decorate the rood screen are also by Notke.
Since the war, the famous altar of Hans Memling has been in the medieval collection of the St. Annen Museum, but notable polyptychs remain in the cathedral.
In the funeral chapels of the southern aisle are Baroque-era memorials by the Flemish sculptor Thomas Quellinus.
