Móricz Zsigmond körtér is a square in Budapest, Hungary.
Located in Újbuda, or Budapest's 11th District at the convergence of some of Budapest's major boulevards Béla Bartók ut and Villanyi ut, the square in close proximity to the River Danube. From 1929, the square was initially named after Miklós Horthy, but was renamed after famous Hungarian writer Zsigmond Móricz in 1945. It remains a prominent location within the city, and was a scene of fierce fighting in the 1956 Hungarian Revolution.
Budapest's new M4 metro has a stop at the square.
The main feature of the intersection is the gomba, or mushroom. This building, constructed in 1942 in the middle of the roundabout, featured shops as well as the electrical transformer distributing current to the significant tramway network. As it was in poor condition, the mushroom was earmarked for redevelopment in line with Budapest's cultural district and construction of the M4 metro. The building was fully renovated by the summer of 2014.
