The city's tourism office lists the sites and says each sets its own hours; the regional portal of Castilla y León publishes the hours above. The Convent of Santa Teresa, at Plaza de la Santa inside the walls, is the place to start: the chapels of El Carmen and La Santa stand on the rooms where Teresa de Cepeda y Ahumada was born in 1515, Mass is celebrated on weekdays at 9:00 a.m., 1:00 p.m., and 8:00 p.m. (8:30 p.m. June to September) and on Sundays at 9:00, 11:30 a.m., 12:30, 7:30, and 8:30 p.m., and visits are not allowed during services. The relics room beside it holds reliquaries, her writings, and musical instruments she used; the crypt museum is separate.
La Encarnación lies outside the walls on the north side. Teresa entered it in 1535 and spent nearly four decades there, was counseled by Francis Borgia, John of the Cross, and Peter of Alcántara, and planned the Carmelite reform from inside it; the museum keeps a drawing of Christ crucified by John of the Cross, and the Transverberation chapel of 1717 marks the site of her vision. San José, founded August 24, 1562 and still an active convent, shows her cell, refectory, and kitchen. The Cuatro Postes viewpoint across the river, built 1566, recalls the childhood attempt to run off to the Moors.
In October the tourist office runs a Saturday Huellas de Teresa guided walk at 10:30 a.m. from the visitor center for 8 euros, monument entry included. The existing page on St. Teresa sites in Ávila gives the devotional background; this one carries the hours.
