Located in the heart of the city, but just outside the walls, it dates from 1887. The Guild Hall is named in honour of the London guilds and has got a Gothic architectural style, similar to its counterpart in London. The original building cost £19,000 to build and was officially opened in 1890 as the administrative centre of the Londonderry Corporation. In 1908 it was razed to the ground. The building stands on land reclaimed from the River Foyle. The Guild Hall houses Mayor's Office and council chamber. The red sandstone building is of neo-gothic architecture; with Tudor overtones. In 1972, the Guild Hall was partly destroyed and carefully restored and reopened in 1978. The interior houses some of the finest examples of stained glass windows in Ireland with many having been restored using the original watercolour designs. The council chamber on the ground floor is the seat of Derry City Council.
