Arenberg Castle, Salzburg

Arenberg Castle, Salzburg, Austria, stands as an early 17th-century château later reshaped in the 19th-century Biedermeier manner, and its history links medieval church ownership, noble residence, religious education, and modern cultural use. The place appears in records from the 14th century under the cathedral chapter, and over the centuries it has changed hands and functions in ways that reflected shifting social and institutional needs in Salzburg. Its grounds yielded a substantial Roman burial ground during park works in the late 18th century, and the property today falls within the right-bank Old Town that is part of the city’s UNESCO-protected historic centre.

In the 16th century the site served as the seat of regional nobility, first held by the lords of Pirglstein and later by the lords of Rehlingen. In the 17th century the archbishop Johann Ernst von Thun acquired the estate and in 1695 transferred it to members of the Ursuline order to provide living quarters and a school for girls. The location proved unsuitable for their plans, and the nuns began building a new convent and school on Gstättengasse, with work starting in 1699 and finishing around 1720. After the Ursulines departed, the former castle accommodated teaching activities connected with the diocesan seminary.

At the end of the 18th century the estate entered private hands when Rosenegger purchased it in 1791 and laid out an extensive landscape park in the fashion of English gardens. Excavations made during those works in 1792 uncovered a large Roman cemetery along with movable treasures. A major fire in 1814 led to rebuilding in the Biedermeier idiom that shaped the castle’s present appearance. The geologist Eberhard Fugger was born there on 3 January 1842. In 1861 Princess Sophie of Arenberg, née Princess of Auersperg, acquired the property and enlarged the house by joining two three-storey wings with a new central section.

During the early 20th century the castle housed the writer and thinker Hermann Bahr and his wife Anna Bahr-Mildenburg, an opera singer and co-founder of the Salzburg Festival, from 1912 until 1922. Ownership passed in 1931 to the city and state of Salzburg together with the Salzburg Savings Bank. In January 2001 the Salzburg Stiftung of the American Austrian Foundation bought the property to establish an international conference centre for physicians, scientists and artists; after renovation the building reopened around 2005. On 20 April 2009 welding work sparked a fire that destroyed the roof truss; the roof was rebuilt and the centre resumed operations in April 2010. The castle and its grounds remain part of the historic core on the Salzach’s right bank.
