In the imperial jurisprudence, houses in which heretics held their conventicles were forfeited to the Church and this provision was adopted in the legislation of Alfonso X.[341] When prosecution was systematized in the thirteenth century, this was modified to tearing down all houses in which heretics were found, the site remaining forever accursed and unfit for human habitation. This was accepted by the Church and found its way into all the lands that admitted the Inquisition.[342] Aragon adopted it and when, about 1340, the Spiritual Franciscan Fray Bonanato was burnt, and his disciples were scattered, the building which they had occupied at Villafranca del Panadés, near Barcelona, was levelled to the ground.[343]
In the early days of the Spanish Inquisition, the strict enforcement of the rule would have led to great destruction and serious impairment of the value of confiscations. It seems therefore to have been reserved for buildings in which the heretics or apostates had been accustomed to assemble, and then the king, as the recipient of confiscations, decided the matter. A letter of Ferdinand, May 23, 1501, to Aliaga his receiver at Valencia, states that the inquisitors have asked him to decree the destruction of a house in which a synagogue had been found, to which he assents with the suggestive addition that the civic authorities must be ordered to offer no opposition. It turned out that Ferdinand had already given the house to Juan Pérez, the scrivener of sequestrations, whereupon he ordered Aliaga to have it appraised and to pay the value to Pérez.[344] He seems to have offered no opposition to Lucero's operations in Córdova, where a number of houses were torn down as having served as synagogues, and he ordered them rebuilt when the Congregacion Católica assembled at Valladolid, in 1509, pronounced the prosecutions fictitious.[345]
When the confiscations passed to the Inquisition, financial considerations apparently got the better of zeal, for when, in 1539, at Valencia, trials of a number of Judaizers revealed that a crucifix had been maltreated in a house used for their assemblies, and the tribunal desired authority for its destruction and the erection of a memorial chapel, the Suprema replied cautiously with a number of questions as to value, location and expense, as there were no funds for the purpose, and it ordered the auto de fe to be held, reserving decision as to the house.[346] The subsequent proceedings against the convicts, who revoked their confessions, show that the house was still standing four or five years later.
