Vindonissa museum, Archaeological museum in Brugg, Switzerland

Vindonissa Museum is an archaeological museum in Brugg, opposite the old town at Eisiplatz, showing finds from the Roman legionary camp of Vindonissa in neighbouring Windisch. Its Art Nouveau building, opened in 1912, has a three-storey main block with two tower-like corner projections and a five-arched loggia in the garden. Stucco medallions on the long wall depict the emperors Nerva, Domitian, Vespasian and Nero.

The museum building was constructed in 1912 in Art Nouveau style after architect Albert Froelich won a design competition. Its founding followed growing interest in the Roman sites in the region.

The interior spaces are designed after Roman house layouts, with mythological representations adorning the columns of the upper floor created by Werner Büchli. This design helps visitors imagine how people actually lived during that time.

The museum stands at Eisiplatz, opposite Brugg's old town, and is run as part of the Römerlager Vindonissa under Museum Aargau. Guided tours and workshops are offered for adults and school classes, and further exhibition rooms and sites lie in neighbouring Windisch. The building keeps its original 1912 state, so the two exhibition halls and the upper-floor columns are seen as built.

The building's roofline, with a large hipped roof pierced by smaller hipped roofs and corner towers, alludes to the west gate of the Roman legionary camp of Vindonissa, though it is not a reconstruction. The design was copied in 1922 for the Provinciaal Museum in Nijmegen.
