Andrássy út, 20, Neo-Renaissance palace on Andrássy Avenue, Terézváros, Budapest, Hungary

The Gomperz Palace at Andrássy Avenue 20 is a listed palace in the Terézváros district, next to the State Opera, built from 1879 to 1881 to plans by Vilmos Freund for the banker Zsigmond Gomperz von Denta. It replaced a classicist apartment house from 1840 that was demolished in 1878. Today it houses the Embassy of Ecuador.

A classicist house built in 1840 for Anton Argauer to plans by Ferenc Kasselik stood here until its demolition in 1878, during the extension of Andrássy út begun in 1872. The Moravian-born banker and merchant Zsigmond Gomperz von Denta bought the plot and had Vilmos Freund design the present palace, built 1879–1881.

The palace's ground floor housed cafés: Károly Seemann opened Café Szecessió here in 1883, and in 1911 Bertalan Weisz bought it and renamed it Café Windsor. Today the building serves as the Embassy of Ecuador, so the former café rooms are not open to the public.

The building sits directly on Andrássy Avenue and is easy to reach from the street. Since this is an active residential and commercial property, visitors can appreciate the facade from outside.

The palace's plot held an 1840 Neoclassical house by Ferenc Kasselik, demolished in 1878. Banker Zsigmond Gomperz von Denta, from Moravia, bought the land and had Vilmos Freund build the palace in 1879–1881. From 1883 Károly Seemann ran the Café Szecessió here, renamed Café Windsor by Bertalan Weisz in 1911.
