Kaiservilla Bruckneudorf, Roman palace complex in Bruckneudorf, Austria

Kaiservilla Bruckneudorf is a Roman villa complex on the Heidwiesen between Bruckneudorf and Parndorf. Its final phase, dated to after 350 AD, had 34 rooms, several with mosaics and wall paintings, and a 12.5-hectare walled area with baths and farm buildings. Over 300 m² of the largest mosaic complex found in Austria are kept in the Landesmuseum Burgenland in Eisenstadt.

The residence was built and rebuilt over several centuries, starting in the 1st century and ending with its transformation in the 4th century. This long building history shows how the structure and purpose of the complex changed over time.

The villa's mosaics, the largest surviving complex on Austrian soil, covered 500 m², of which over 300 m² remain; they are displayed in the Landesmuseum Burgenland in Eisenstadt. Wall paintings divided the rooms with painted half-columns and included a scene of a grazing doe, a young shield-bearer and a building with stairs.

The villa lies on the Heidwiesen meadows between Bruckneudorf and Parndorf, a short detour off the road linking the two villages. The excavated mosaics, over 300 m² of the original 500 m², are not on site: they are displayed in the Landesmuseum Burgenland in Eisenstadt, so plan the two visits together.

A gravestone from the early 2nd century was later reused as a drain cover in the villa. It names M. Cocceius Caupianus, read as princeps civitatis Boiorum, and his wife Cocceia Dagovassa; a second stone names Iunia Cocceia, likely the same family of early owners.
