Not quite. It was a fortified military compound built sometime in the 1700's and then later abandoned. Most likely disease wiped out the native converts, the nearest Bishop probably then ordered the priests back to the nearest Spanish city, and the Garrison stationed at the fort for their protection followed suit. It likely wasn't in use long enough for the missionaries to consider acting on any long term plans for the site beyond digging a well.
However, that's all speculation on my end.
