7 Warszawska Street in Białystok, Palace at Warszawska Street in Białystok, Poland.

Pałac Tryllingów at 7 Warszawska Street is a two-storey urban palace built in 1898–1899 in an eclectic style, with a stucco-decorated facade. Above the entrance and in a decorative cartouche appear only the initials "ET", for Helena (Elena) Trylling, the widow of the founder.

Chaim Abram Trylling, a cloth manufacturer, began this residence on Warszawska Street in 1898 and died in 1899 before construction ended. The palace then passed to his widow Helena, whose initials "ET" appear above the entrance and in a decorative cartouche. The firm "Trylling i Syn" operated until 1932; their son Anatol sold the building before World War II and the family left for the USA. After the war the state took it over as abandoned property, and in 2011 the city of Białystok became owner through an exchange with the CBA.

The initials "ET" above the entrance and in the decorative cartouche refer to Helena (Elena) Trylling, the widow who owned the palace after the founder's death. The building stands on the Białystok manufacturers' trail, a route linking the city's 19th-century industrial families.

The palace is located near the city center and is easy to reach on foot. The exterior is accessible to visitors who want to view the architectural details from different angles.

The initials "ET" above the entrance and in the decorative cartouche refer to Helena (Elena) Trylling, the widow who inherited the residence after the founder Chaim Abram Trylling died in 1899 before construction ended. The palace stands on the Białystok manufacturers' trail.
