The Cloister of the Old Cathedral is a construction of transition from Romanesque to Gothic. Built during the reign of D. Afonso II (1218-1223) it was however programmed since 1176. It would be D. Afonso II who would give a greater incentive to the construction of the Cloister, because he intended that the remains of Chancellor Julião Pais be deposited there. It will be in this Cloister that Portugal's first episcopal school will function. It is also here that there is the tomb ark of D. Sizenando Davides, conqueror of the city in 1064 and responsible for the construction of numerous churches in the Diocese of Coimbra. It is the same D.Sizenando who founded the Cabido da Sé in 1080. In each gallery there are two twin round arches surrounded by a larger pointed arch. Serving as a transition between the pointed arch and the Romanesque arch are rosettes, all of them distinct.
