Ambassador Theatre

The Ambassador Cinema was Dublin's longest-running cinema and was operational on and off until 1999. It operated as a music venue between 2001 and 2008. The Ambassador's current use is as an exhibition hall & event centre.

The building was constructed as part of the Rotunda Hospital in 1764 as an assembly hall and social rooms on what is now called Parnell Street.

From 1897 onwards, the venue was given the name Rotund Room and hosted a number of "moving picture" screenings which were a great novelty at the time. From about 1908 onwards, it was used more regularly to show film presentations and in 1910 it became a full-time cinema, with 736 seats, a basic layout at the time.
