Summerhouse
A summer house was in courtly culture of the Renaissance and Baroque periods, a meeting house for parties, receptions and social events. Here larger and smaller festivities were organized, aligned and danced feasts.
The summer house accommodation, ballrooms, theaters and collections as a cabinet of curiosities; so it was a forerunner of the later Court Theatre.
Famous examples are the summerhouse Vienna, like the New Stuttgart or the new summerhouse Berlin.
It is not the same as a brothel.
