Which San Antonio mission is the oldest?

The missions moved, and that is the whole answer

Almost everyone assumes these four were founded where they stand. Three of them were not. Mission Espada, Mission Concepción and Mission San Juan were all established in East Texas first, and all three were transferred to the San Antonio River in 1731. Two of them arrived on a single day, 5 March 1731. Only Mission San José has stood in one place since it began.

Once you know that, the question stops having one answer and starts having three, and each of the three is on nps.gov.

Oldest by founding: Mission Espada, 1690

The Park Service does not hedge this one. Its own page for the mission says: “This was the first mission in Texas, founded in 1690 as San Francisco de los Tejas near present-day Weches, Texas.”

So the oldest foundation in the park is the one at the far southern end, twenty-six years older than the next two and thirty years older than Mission San José. It came down to the river on 5 March 1731 and was renamed San Francisco de la Espada. If somebody asks which mission is oldest and wants a single name, this is it — and it is the one most day trips run out of time before reaching, because it is furthest from town and the bus does not go there.

Oldest on the San Antonio River: the Alamo, 1718

A different question with a different answer. The Park Service history page puts it this way: “Beginning in 1718, five mission communities formed along the San Antonio River.” The one that began in 1718 is Mission San Antonio de Valero, which is the Alamo — the first of the five on this river, two years before Mission San José and thirteen years before the three transfers arrived.

It is also the one that is not part of the national park. The State of Texas owns it through the General Land Office and Alamo Trust, Inc. runs it, so if this is the answer you were after, the practical arrangements are entirely different — free to enter, but reservations are required. The Alamo page has all of it.

Oldest continuously on its own site: Mission San José, 1720

Its Writ of Possession was signed on 23 February 1720, and it is the only one of the four that has never been anywhere else. Every other mission in the park has an East Texas prehistory and a moving date; this one has a founding and nothing else.

If what you actually mean by “oldest” is “which of these has been standing here longest”, that is the answer, and it is a much less well known one than the 1690.

The oldest building is a fourth question

Founding a mission and building the church you can walk into are separated by decades, and the order changes completely once you ask about the stone rather than the institution. Here is what the Park Service publishes.

Which produces a genuinely odd result: the only mission never to have moved has the youngest church of the three with dates, and the oldest foundation in Texas has a church a year younger than Mission Concepción’s. Age of institution and age of fabric are simply not the same measurement.

One further note, in keeping with how this site works. There is a superlative about Mission Concepción’s church that is repeated across a great many pages and does not appear anywhere in the Park Service material we checked. It is therefore not repeated here. What the Park Service does say about that church — why its painted decoration survived when the others did not — is on which mission to choose, and it is more interesting than the superlative.

What to do with the answer

If the 1690 is what you came for, that means a trip to the southern end of the park, which is one of the two missions VIA route 42 does not reach — a car, a bike or a tour, as set out on the transport page. If the 1718 is what you came for, that is downtown and needs a reservation. If it is the 1720, that is the mission with the visitor centre, the film and two ranger walks a day, so it is also the easiest of the three to build a morning around — and the order to take them in explains why the ranger timetable settles that better than the map does.

All five, with their full formal names and what the park publishes about each, are on the five missions. The 2015 inscription that covers all of them plus a ranch is on the World Heritage page.

Whichever answer you wanted, none of the four park missions charges anything — entry, parking, the ranger walks and the film are all free. The Park Service pages behind the fees, the hours and the church information all still carry a last-updated date of 5 May 2025. Nothing on them looks unstable, but they are the pages this site leans on hardest, so check nps.gov/saan before you travel rather than after.
