A major attraction of the city is Gloucester Cathedral, which is the burial place of King Edward II and Walter de Lacy, and features in scenes from the "Harry Potter" films. Other features of interest include the museum and school of art and science, the former county jail (on the site of a Saxon and Norman castle), the Shire Hall (now headquarters of the County Council) and the Whitefield memorial church. A park in the south of the city contains a spa, a chalybeate spring having been discovered in 1814.
