Schloss Mörsburg

Description

As a prominent building on the northeastern edge of Winterthur, the Mörsburg occupies an important position in the historical landscape of the canton of Zürich. The castle stands at 511 metres on the southern spur of a ridge that separates Winterthur from the Thur valley and belongs to the area of the Aussenwacht Stadel. Visual connections exist to Kyburg (about 9 kilometres) and to Schloss Hegi (around 3 kilometres); an earlier route to Pfyn and Lake Constance ran close by.

The origin of the complex remains unclear; however, archaeological evidence suggests an early timber fortification and, by the end of the 11th century at the latest, a stone residential tower. In the High Middle Ages the lordship changed hands several times: 12th‑century references associate the castle with the Nellenburgs, and later it passed to the Counts of Dillingen‑Kyburg. Under Hartmann IV of Kyburg the site underwent major expansions in the 13th century; his wife Margaretha of Savoy influenced architectural and design decisions. Subsequently the Mörsburg was held as a fief by various local families, including the Meyer von Mörsberg and later the Goldenberger, until the city of Winterthur acquired the castle in 1598. The city used it as an administrative seat until 1798; military conflicts in 1799 badly damaged the structure. After decades of vacancy, the Historisch‑Antiquarische Verein Winterthur established the castle as a museum around 1900; until 2000 a castle warden was housed in the building. Since 2016 the complex has been managed in cooperation with the Historischen Verein Winterthur and a neighbouring hospitality business.

Excavations have provided architectural evidence of burn layers from the 11th century. Major alterations took place in the 12th and 13th centuries: the original tower, with walls 1.30 metres thick, received a megalithic casing and a U‑shaped extension on the garden side; even before this casing the enclosing wall was built, with a zwinger‑like forebuilding that today serves as a stairwell. The square tower footprint measures roughly 16 × 16 metres with walls nearly five metres thick. Around 1240 two additional storeys with large timber halls were added, and an early Gothic chapel with ribbed vaults was installed on the third floor. At its heyday the complex comprised a ring wall with residential and utility buildings on the southeastern terraces; many of these remains were uncovered in 1978/79. Parts of the fortifications were abandoned around 1400, while the tower and enclosing walls were retained. Later archaeological work revealed further medieval structural remains. The city of Winterthur carried out restorations on several occasions over the centuries; extensive repairs were undertaken in the 20th and early 21st centuries.

As a museum the Mörsburg communicates its constructional and usage history. The south garden displays exposed sections of wall. In the cellar everyday implements and presses are exhibited. On the floors are stove ceramics, books, military objects (including those of Oberst Carl von Clais, 1824–1906), firefighting and trade exhibits, tower clocks, the early Gothic chapel and historic living rooms. The fourth floor preserves the large banqueting hall of 1735 and a historic tower oven from the 16th century. Local legends, for example the tale of the Goldenen Kegelspiel with an underground treasure and a liberated maiden, complement the exhibition with folkloric aspects.
