The Forum Barcelona by Herzog & de Meuron. It’s on one end of the Diagonal, which is a very long and straight diagonal road that slices across the city. The other end is the university, where the Escola Tècnica Superior d’Arquitectura is located. The Torre Agbar is somewhere in them middle.

You can see David, Jeff and me in the reflection of the ceiling lobby underneath the Forum’s main exhibition space. Novel materials and many little places to explore, but oddly this part of town still feels deserted.
