Andravida is a city in Elis in the northwestern Peloponnese. It was the primary residence of the prince of Achaia. According to the Chronicle of the Morea, Andravida was already a town before the Frankish conquest, but was not fortified.
Geoffrey I Villehardouin established himself in Andravida almost immediately after his arrival. Its location in the rich Elean plain allowed it to be well supplied for the great gatherings the Frankish chivalry so enjoyed, while its proximity to the sea, through the port at Clarenza, permitted easy contact with the West; never fortified, it was protected by the castle of Chlemoutsi 5 km to the east. The city witnessed great assemblies of troops and courtiers, including the marriage of Hugues de Brienne and Isabelle de la Roche in 1277. Geoffrey I transferred the bishopric of Olena to Andravida and it kept that title, although the bishop was a Frank. 
No monuments from before 1204 are known, but three churches of the Frankish period can be identified in the sources: St. Sophia, St. Stephen, and St. James. The latter possessed a hospital and was the burial place of the Villehardouins. The sanctuary and side chapels of the Dominican Church of St. Sophia survive. It was an enormous cathedral, more than 41 m long and nearly 19 m wide. It can be paralleled by many late 13th- and early 14th-centuries Gothic churches in France and Italy. Its plan resembles that of St. Paraskeve in Chalkis. Inside the church was the tombstone of the princess Agnes (died 1286), with what is probably the coat of arms of the Villehardouin family.
