What types of permanent settlements did the spanish establish in north america?

The Spanish established permanent settlements in North America. The first settlement was a Spanish fort called St. Augustine in Florida. It was established in 1565. Its primary function was that of a base camp for explorers who explored the continent. It was also used as a centre to convert the local Native Americans to Roman Catholicism. There were a few settlements established in outlying areas. These did not last. They were either attacked and destroyed by the Native Americans, or they had to close because they could not support themselves economically. 

It should be at the center of any map going vertically: the prime meridian, as it passes through greenwich,  england, is considered 0 degrees longitude

There is lots of evidence
