Part of my PhD on museum closure is about the Welsh Industrial and Maritime Museum. The museum stood on the waterfront of Tiger Bay, the part of Cardiff once filled with canals and large docks. In the late 1980s and 1990s, the Cardiff Bay Development Corporation redeveloped the area, renaming it as Cardiff Bay in the process. During the redevelopment, the Corporation bought the industrial museum’s site and sold part of it to a property developer. The Mermaid Quay shopping centre opened on the site in 1999.
These photos show the transformation of the bay area. The bay was tidal, and mud flats were exposed when the tide was out. That changed when the bay was enclosed with a barrage to raise the water level to a consistent height. The black and white photos were taken in 1979, two years after the Welsh Industrial and Maritime Museum opened. I took the colour photos in February 2022.
