De Cosmobar, Rotterdams langst bestaande gaycafé, is officieel geopend in 1937 op de Westzeedijk in het voormalige havenkwartier en dus veel door zeelui bezocht die Rotterdam aandeden. Na de oorlog werd de Cosmo meer en meer gaycafé en verhuisde het naar het Westplein en later naar zijn definitieve locatie aan de Schiedamsesingel. English version:
The Cosmo bar, Rotterdams longest existing gay bar
, officially opened in 1937 on the Westzeedijk in the former harbor area. It was regularly frequented by sailors visiting Rotterdam. During the second World War the bar managed to stay open and during that period it was visited by German soldiers. After the war it became more of a gay bar than before and moved to the Westplein and eventually to its definitive location on the Schiedamsesingel.
