San Domenico, a Gothic edifice originally designed by Giovanni Pisano but rebuilt in 1614, contains the monument of Pope Benedict XI.
(attributed, but probably wrongly, to Giovanni Pisano by Vasari), and in its east front a Gothic window with stained glass by Fra Bartolommeo of Perugia (1441).
It was imitated by Giovanni Pisano in his monument to Pope Benedict XI.
The arsenal, which was famous in Dante's day, received its first enlargement in 1304, when, on the design of Andrea Pisano, new building sheds and the rope walk or Tana were erected.
The splendid west front, of tricuspidal form, enriched with a multitude of columns, statues and inlaid marbles, is said to have been begun by Giovanni Pisano, but really dates from after 1370; it was finished in 1380, and closely resembles that of Orvieto, which is earlier in date (begun in 1310).
