A.Siemssen Apartment House at Friedrich Str., Historical apartment building in Qingdao, China

The A. Siemssen Apartment House at 72 Zhongshan Road is a two-storey brick, stone and timber building with a basement and a pitched-roof attic, covering about 1,500 square metres on a 2,000-square-metre plot. Its east entrance has a two-storey pilaster crowned by a triangular gable with a peacock relief, and the roof carries three small spires and panels of coloured square tiles forming four geometric patterns.

Built in 1906–1907 by the German real-estate firm Xiangfu Yanghang (Alfred Siemssen) as rental apartments, it was designated Building 5 in Block G, after two earlier apartment blocks at today's Feicheng Road 15 and 17. Japan confiscated the property in 1914; after 1922 it was retained by the Japanese consulate. Around 1924 the Qingdao General Chamber of Commerce moved in from Guantao Road, and in 1931 it became the Qingdao City Chamber of Commerce.

The building is now the Zhongshan Road Urban Memory Museum, opened on 29 September 2022. Its name recalls the Qingdao Chamber of Commerce, which moved here from Guantao Road in 1924 (some sources say 1923) and was reorganized as the Qingdao City Chamber of Commerce in 1931.

The building stands at 72 Zhongshan Road, at the northwest corner of its junction with Feicheng Road, in Shinan district. It now houses the Zhongshan Road Urban Memory Museum, which opened on 29 September 2022, so visitors can go inside during opening hours. The main entrance is on the east facade, under a two-storey pilaster and a triangular gable.

The roof is covered not with the usual red or grey tiles but with a rare square slab material, inlaid with borders of different colours forming four geometric patterns; it was later replaced with ordinary rectangular red tiles. The east facade has a two-storey pilaster crowned by a triangular gable with a peacock-display relief.
