The Monastery of the Dominicans of Batalha was built to commemorate the victory of the Portuguese over the Castilians at the battle of Aljubarrota [webmaster's note: hence the name Batalha] in 1385. It was to be the Portuguese monarchy's main building project for the next two centuries. Here a highly original, national Gothic style evolved, profoundly influenced by Manueline art, as demonstrated by its masterpiece, the Royal Cloister.
