building in Brugg to be constructed beyond the town's wall was the Stadthaus (Town House), also known as the Palais Frölich. It was built at the behest of Johann Jakob Frölich, who acquired his wealth through his service as private secretary to Earl Sandwich. The baroque building, which is topped by a mansard roof, is adorned by baroque elements internally as well as externally. It has been the seat of the town's administration and council since 1909. To the west of the building is the Stadtpark (Town Park) with two abutting neo-classical office complexes. There are a number of other noteworthy buildings in the direct vicinity of the Stadthaus. The "Haus Rauber" is the only neo-classical cottage in Brugg. It was built in 1822 according to the plans of Architect Hans Conrad Stadler. The "Schilplinhaus" was completed in 1810 during the late phase of rococo architecture and was acquired by the Schweizerischer Bauernverband (Swiss Farmers’ Union / Association) in 1928. The "House of the Swiss Farmer" (Haus des Schweizerbauern), a large administrative building, was constructed on the location of the Schilplinhaus' barn. The town's Catholic house of worship – the St. Nikolaus Church – was named after the town's one-time patron saint, Saint Nicholas. It was constructed in 1905 according to the plans of Adolf Gaudy in a neo-baroque style and was completely renovated in 1952. Located about one kilometer to the west of the old town, in Altenburg, on top of a crag is the small castle "Schlössli Altenburg," which was constructed on the ruins of a Roman fort during medieval times and was the first residence of the Habsburgs. Integrated into the western wall of the tower house is the highest remaining Roman wall in Switzerland, the construction material of which comes primarily from the 16th century. It has served as a hostel since 1943. The industrial heritage path (Industriekulturpfad) Limmat-Wasserschloss is a trail towards Wettingen, which passes by forty-four different industrial buildings. Structures in Brugg along this trail include the Altenburger railway bridge, the former electric power station, Brugg's train station, a number of different plants of the Kabelwerke Brugg, and the town's decommissioned gas plant.
