The south wall of the church of Sant'Antonio Abate, just outside the old city walls near the train station, carries one of Keith Haring's largest and last murals — 180 square metres of interlocking figures painted in the summer of 1989. The title means "all the world", and the thirty cartoon figures represent peace, harmony, and the cycles of life in Haring's instantly recognisable style.
It is a five-minute walk from the station and worth the detour for anyone passing through. The wall has been carefully restored, and the small square in front now has a few cafés where you can sit and look at it. Most tourists in Pisa never see it, which feels appropriate for a work that was supposed to be public art for the residents.
