The walls, towers and elaborately carved stone gateways to the city of Avila are indeed majestic. And while others have commented on the churches outside the walls, my favourite is the Hermitage of San Segundo, a small building nestled beside the Adaja river. From here I crossed the river and walked up to the Four Posts monument, from where there is a panoramic view of the city walls from the west. From the lookout bus #7 goes back to the station.
