In the early fifteenth century, Franciscan Third Order Regular communities began to be established in Ireland. In 1445 the archdeacon of Connor was sent a mandate by Pope Eugenius VI, authorising him to establish a Franciscan Third Order Regular friary in his diocese.
A 1580 map of the County Antrim coastline shows the friary at ‘Glanarme’ on the other side of the river from the castle. It was probably closed by the beginning of the seventeenth century, but its site continued to be the favoured burial place of the local population, including settlers from Scotland.
Little of the friary survives today, and what remains is not easy to interpret. It was aligned along the traditional east-west axis, so what was once thought to have been the chancel is now believed to have been a transept.
The city walls of Avila were built in the 11th century to protect the citizens from the Moors. They have been well maintained throughout the centuries and are now a major tourist attraction as well as a UNESCO World Heritage Site. Visitors can walk around about half of the length of the walls.
The layout of the city is an even quadrilateral with a perimeter of 2,516 m. Its walls, which consist in part of stones already used in earlier constructions, have an average thickness of 3 m. Access to the city is afforded by nine gates of different periods; twin 20 m high towers, linked by a semi-circular arch, flank the oldest ones, Puerta de San Vicente and Puerta del Alcázar.
