Pisa - Chiesa del Santo Sepolcro

Already existing in 1113, the octagonal "Church of the Holy Sepulchre" was built for the Knights Hospitaller (aka "Order of the Knights of Saint John"). It was designed by Diotisalvi, who later designed the Baptistery of Pisa Cathedral. His name is inscribed on a wall of the tower ""Huius OPERIS FABRICATOR DeuTESALVET nominatur».

The church was locked, but I found a window. Inside around the altar is a rotunda out of eight pillars - and a kind of ambulatory around the center. This interior rotunda is "generic" for churches of the "Holy Sepulchre", eg "Neuvy-Saint-Sépulchre", "Drueggelte", "Northampton"..
