This house, however, is not, as has been so frequently and erroneously stated, the one in which Columbus was born. It has long since disappeared, to make way for the enlargement of the neighbouring hospital. The Porta (or Gate) Olivella stood for centuries to the right of the church of San Stefano. As this house is very often mentioned in deeds of the period of the last half of the fifteenth century as belonging to the family of Domenico Colombo, we are able to trace its history with fair accuracy. It formed part of the dower of Susanna Fontanarossa, for, as we have already seen, it could not be sold without her permission. It is probable that the family, instead of living in it, was in the habit of letting it. On more than one occasion the tenant did not pay his rent, and in 1476 Domenico Colombo had to come from Savona to Genoa to exact it. Unable to get the £20 due to him for arrears, he raised (through his notary, a certain Signer Camogli) a loan on the sum, the tenant, Malio, becoming a guarantee for the amount of his unpaid rent--"Occasione pensionis euiusdem domus ipsius Dominici quam tenet et conducit, etc." Domenico Colombo possessed yet another house, still standing, and situated close to the recently restored Gate of Sant Andrea, at the top of the long, steep street still called Portorio. In this venerable building Christopher Columbus was unquestionably born, in 1451. Four years before the discovery of America by his illustrious son, Domenico Colombo, being in reduced circumstances, was obliged to transfer this house to his son-in-law Bavarello, the husband of his only daughter Bianchinetta. The papers relative to this proceeding are still in existence, and bear the date July 30, 1489. Domenico Colombo certainly lived here with his wife and family from 1435 to 1470, when they went to Savona. This is proved by the register of the monastery of San Stefano, in which they are regularly entered as paying a yearly ecclesiastical tax to the Prior during the whole of this period. They left Genoa in 1470, and resided at Savona until 1484. The Savonese archives, however, contain frequent mention of Domenico until 1494, when he again returned to Genoa, where, in all probability, he died, some years later. In the deed authorising the sale of the house in Porta Olivella, the witnesses are "Christopher Colombo and Giovanni Pellegrino, sons of Domenico and Susanna Colombo."
