The Colombischlössle is a manor house in the city centre of Freiburg im Breisgau where the eponymous archaeological museum is situated. Building The "Colombischlössle" (Colombi castle) was built between 1859 and 1861 on the terrain of the former bastion Saint Louis of the town fortification of Freiburg, which had been filled in 15 metres and converted to a garden. Duches Maria Antonia Gertrudis von Zea Bermudez y Colombi was the one who commissioned the castle. She wanted the building to be her widow's residence. The plans were made by the Freiburg architect Georg Jakob Schneider, who chose the gothic Tudor-style of the English medieval times as inspiration for the historicist mansion. Additionally, he was inspired by his teacher, Friedrich Eisenlohr, who had rebuilt Ortenberg Castle in this style. It cost about 300,000 Goldmark, 750 per square metre. The historic stairwell, the parquet flooring and a light glass cupola roof, still show the former prosperity of the duchess Maria Antonia Gertrudis de Colombi y de Bode (1809–1863). Johann Georg Thoma, a manufacturer from Todtnau, acquired the estate from the inheritors and converted part of it into building terrain. Around this time, the Colombi street and Rosa street, which was named after his wife, were formed here. In 1899, the city of Freiburg purchased the building. It served as the urban art museum from 1909 to 1923, and later as an office building. Additionally, the Badian association "Badische Heimat" had an office here, as their secretary, Max Wingenroth (1872–1922), was the head of the town's collections. From 1947 to 1952, the Colombischlössle was the location of the "Staatskanzlei", the regional government of Baden under Leo Wohleb. Since it was renovated in 1983, the "Archäologische Museum Colombischlössle" (archaeological museum Colomischlössle) has its home in the Colombischlössle. The Colombischlössle and its park have been designated as a national heritage site since 2003. The museum was closed due to remediation work from May to September in 2014. During this time, the historical glass roof was resealed and the walls on the ground floor were repainted. Park The park of the Colombischlössle was designed in the style of an English landscape garden with exotic plants and trees as well as a fountain. It was completed in 1860 and is open to the public since 1906. In 1955, the park was appointed a natural monument. Opposite to it, the Colombi Hotel was opened in the middle of
