Catedral Metropolitana do Rio de Janeiro is the seat of the cardinal archbishop of Rio de Janeiro, Brazil. It is dedicated to Saint Sebastian, the patron saint of Rio de Janeiro. The current church was built between 1964 and 1979 and replaced a series of old churches that had served as cathedrals since 1676. It is located in the centre of the city. Conical in form and with a 96 metres internal diameter and an overall height of 75 metres, it has a standing-room capacity of 20,000 people.
The cathedral's four rectilinear stained glass windows soar 64 metres from floor to ceiling.
