The famed apse with a vault that radiates from a central column, sometimes called the 'Palm Tree' in the Jacobin church in Toulouse, was built c.1245-1252. The church was dedicated in 1385, and the great Dominican and Doctor of the Church, St Thomas Aquinas is buried there.

The French Dominicans had acquired the name 'Jacobins' because their first priory in Paris was near the church of St James (Jacobus).

Built between 1299-1301, this is the entrance of the Chapter House of the medieval Dominican convent in Toulouse, which is now owned by the French State.

Sta Pudenziana is one of the oldest churches in Rome, thought to have been built over a thermal hall, c.390. Much of the existing building dates from a rebuilding in 1589, but the splendid apse mosaic survives from the 4th-century. It depicts Christ as Lord and Protector of the Church, and he has St Paul and the Church of the Gentiles on the left, and St Peter and the Church of the Jews on the right.

Much of the basilica of Sta Pudenziana dates to the 16th-century but the entrance portal seems to utilize columns and stone carvings from an earlier building.
