It was built when King Manuel I granted a new charter in 1510. It is a cage pillory crowned with an armillary sphere and topped with a cross and based on an octagonal column and capital. It was a symbol of municipal authority, justice and independence and was built in the town’s main square in front of S. Pedro Church. This was the site of the newly constructed Town Hall. This was where fairs and markets took place and it was there that later Misericórdia House and the former Santa Clara Convent were built. The pillory was classified as a National Monument in 1910.
