Alessandro Valignano
Resisting calls for the dangerously leaning structure to be demolished, from 1990 to 1995, the ruins were excavated under the auspices of the Instituto Cultural de Macau to study its historic past. The crypt and the foundations were uncovered, revealing the architectural plan of the building. Numerous religious artifacts were also found together with the relics of the Chinese Christian martyrs and the monastic clergy, including the founder of the Jesuit college in Macau, Father Alessandro Valignano.
