Glasscherbenvilla, Architectural heritage monument in Passau, Germany.

The Glasscherbenvilla, also called the Ostuzzi Villa, is a residential house on Ostuzzistraße in Passau, built under the direction of the Italian-born master builder Aristide Ostuzzi and completed on 9 September 1902. It mixes Italian Renaissance and Baroque elements with touches of Art Nouveau, and has a gable dormer and two bay windows. All facades carry lavish decoration in stucco, glass, porcelain, terracotta and mortar.

Aristide Ostuzzi, an Italian-born master builder in Passau (1853–1926), erected the house under his own direction and completed it on 9 September 1902. The building had fallen into disrepair by 2000, when it was carefully restored; the two tower spires, previously removed because of damage, were put back in place during that work.

The house is known locally as the Glasscherbenvilla, or shard villa, because its facades are covered with stucco, glass, porcelain, terracotta and mortar. The street where it stands was later named Ostuzzistraße after its builder, Aristide Ostuzzi. Visitors can look for the two bay windows and the gable dormer that break up the decorated surfaces.

The building sits on Ostuzzistraße 5 and is easily reached on foot. The facade is visible from the street, allowing visitors to see the full decoration from outside.

The two tower spires were removed because they had become damaged and were put back only during the 2000 restoration. The house was finished on 9 September 1902 under the direction of its architect, Aristide Ostuzzi, who was born in Italy in 1853 and died in 1926.
