 In 1575, the first reference to a parish seat in Paderne occurred, and records from the local authority show that the change from ecclesiastical seat to parish occurred around 1500.The new church continued to be a priory of the Order of Avis, even as the settlement declined in importance, a decline accelerated after the 1755 Lisbon earthquake when the fortress of Paderne was heavily damaged.The castle of Paderne was purchased in 1997 by the "Instituto Português do Património Aqruitectónico", or IPPA, the forerunner of the National Registry IGESPAR.
