It was the treasury officials’ privilege and duty to reside in the houses of government (casas reales) where the coffer was kept. These buildings varied in number and location along with the relocations of the town. During the 16th century St. Augustine moved about with the sites of the fort. According to Alonso de las Alas, the first presidio, known to him as “Old St. Augustine,” was built on an island facing the site of the town he lived in. St. Augustine was moved “across to this side” when the sea ate the island out from under it. In its new location on the bay front the town had a guardhouse, an arsenal under the same roof as the royal warehouse, and perhaps a customs-counting house at the dock. [Note 65: Alonso de las Alas 1/12/1600; royal officials 1/5/1580 (Council summary 6/4/1580); cedulas to the royal officials 9/30/1580, and the governor and royal officials 4/26/1583] There were no official residences. Three successive governors rented the same house on the seashore—Governor Ybarra thought it a most unhealthful location. This St. Augustine, and a new fort on the island of San Juan de Pinillo, were destroyed by Drake in 1586; [Note 66: Juan de Cevadilla, Havana, 8/18/1586] (Bushnell KC)
