Once inside, the splendid qualities of the building become more apparent. Here is a view of the cross corridor from the stepped entrance hall. The quality and detailing of the materials are what makes this building so special.

Labour and materials were comparatively cheap in the mid 1930s, one of the worst times for Wales economically, and the architect took full advantage of this.

You can see the polished Bath stone walls with their shaped stepped architecture framing the opening to the barrel vaulted coffered ceiling corridor.

The carved keystone above has the face of a Viking warrior reminding the visitor of Swansea's early troubled past.

Sean Kier, Swansea's Museums Service Manager showed me around, pointing out the exhibition of Frank Brangwyn's work on the wall of this corridor.
