The Museum of Mosaics (Bulgarian: Музей на мозайките, Muzey na mozaykite) is a museum in the town of Devnya in Varna Province, northeastern Bulgaria. The museum, built on top of a large ruined Roman villa from Late Antiquity, exhibits mosaics from the Roman and early Byzantine city of Marcianopolis, as well as other archaeological artifacts.
The museum was founded as a result of archaeological research beginning in 1976, which uncovered the House of Antiope, a Late Roman villa decorated with floor mosaics. The villa was constructed in the late 3rd or early 4th century AD, perhaps during the rule of Roman Emperor Constantine the Great (r. 306–337). Constructed on the site of earlier buildings destroyed during the Gothic raids in 250–251, it was abandoned in the 7th century due to Avar and Slavic invasions.
The villa is nearly square in shape, measuring 37.15 m × 37.75 m (121.9 ft × 123.9 ft). It features 21 rooms situated around an inner courtyard (atrium) with a well; the rooms have a total area of 1,409 m2 (15,170 sq ft). The museum lies in a small park, with a well-preserved Roman street crossing under the building. Around the museum are several ancient walls, which, along with the villa, constitute most of the preserved ruins of Marcianopolis. The museum building only covers the western part of the villa; its eastern wing and the atrium are not covered. Many of the villa's walls were decorated with frescoes and stucco, while the floors of the portico and five premises were covered by elaborate mosaics. In addition to mosaics, the museum displays items pertaining to the Roman villa itself and to the life of its inhabitants.
