Monastery of Batalha, Batalha probably had the first workshop for stained-glass windows in Portugal. The art was introduced in Portugal by German artists from the regions of Franconia and Nuremberg. The oldest windows date back to the end of the 1430s. But the Manueline, ogival stained-glass windows in the choir date from the 1520s and 1530s and were produced by Portuguese masters, among them Francisco Henriques. They represent scenes from the lives of Christ and Mary: the Visitation, the Epiphany, the Flight to Egypt and the Resurrection of Christ.
