County Hall, the headquarters of Cardiff council, could soon be knocked down and replaced with flats and hotels.
The building overlooks the Bute East Dock in the Atlantic Wharf and was opened in 1988, initially as the home of the former South Glamorgan county council.
But under new plans, as part of the indoor arena redevelopment, County Hall would be replaced with hotels and apartment towers reaching up to 17 storeys tall.
