Answer 1

Its the old fort at St. Augustine.

Answer 2

According to my source cited below:

"The oldest continuously occupied European-founded settlement in the continental United States, St. Augustine was founded by the Spanish. The first Christian worship service held in a permanent settlement in the current United States was a Catholic Mass celebrated in St. Augustine.

A few settlements were founded prior to St. Augustine but all failed, including the original Pensacola colony in West Florida (founded 1559) — which was wiped out by a hurricane a mere two years after its founding, and Fort Caroline in what is today Jacksonville, Florida in 1564.

The city was founded by the Spanish admiral Pedro Menéndez de Avilés on August 28, 1565, the feast day of Augustine of Hippo, and consequently named by him San Agustín. Martin de Arguelles, the first American of European ancestry, was born here one year later in 1566. This came 21 years before the English settlement at Roanoke Island, in Virginia Colony, and 42 years before the successful settlements of Santa Fe, New Mexico, and Jamestown, Virginia."

Also:

"The Oldest House
Our featured attraction, the González-Alvarez House is the oldest surviving Spanish Colonial dwelling in Florida. The site has been occupied since the 1600s and the present house dates to the early 1700s. Since 1893 visitors have toured the house to see evidence of the Spanish, British and American occupations of St. Augustine and to learn how the residents lived. In 1970 the U.S. Department of the Interior designated the house a National Historic Landmark"
