Tubac Presidio State Historic Park
Arizona's first state park preserves the ruins of San Ignacio de Tubac, the Spanish presidio founded in 1752. It's also where the first newspaper in Arizona was printed, which makes it the start of the territorial paper trail our archive files follow.
Access
Arizona State Parks historic site and museum. Hours (as of Oct 2026, check the park site): Tue–Sun 9 a.m.–3 p.m.; closed Mondays. Entrance fees (as of Oct 2026, check the park site): adult (14+) $10, youth (7–13) $3, child (0–6) free. There's no fee to enter the visitor center. The park lists discounts for military, first responders and teachers.
Safety & respect
Southern Arizona heat: carry water, even in October. The presidio is an archaeological ruin. Stay on the paths, don't climb on or touch the foundation walls, and don't collect anything; removing artifacts from state land is illegal. The park's Native heritage exhibits are history, not lore.
Lore note
The park was established to preserve the ruins of the oldest Spanish presidio site in Arizona, San Ignacio de Tubac, founded in 1752. Arizona State Parks lists four Arizona firsts here: the first fort, the first European settlement, the first American mining community, and the first printing of a newspaper. Its collection includes 1700s artifacts and the state's first printing press. It's also a starting point for hiking what remains of the Anza Trail. No anomaly case is set here; it's on the ledger as the place Arizona's press history begins.

In 1752 Spain founded the presidio of San Ignacio de Tubac on the Santa Cruz River. Arizona State Parks says it’s the oldest Spanish presidio site in the state. What’s left are low adobe foundations, shown above, preserved in Arizona’s first state park. A museum next to them covers the site from its archaeological past through the Spanish, Mexican and territorial periods.
Where the paper trail starts
The park lists four Arizona firsts here: the first fort, the first European settlement, the first American mining community and the first printing of a newspaper in Arizona. Its collection includes the state’s first printing press.
That matters to the ledger because so many of our Arizona files are press history: the Phoenix fireball of 1906, Phoenix’s 1898 stone-throwing case, Flagstaff’s April Fool’s airship and territorial Halloween. They all come out of the territorial newspapers that started in places like Tubac. We haven’t yet checked which paper was first, so we don’t name it here.
Safety callouts
Archaeological ruins. The walls are fragile and the ground is uneven. Stay on the paths. Don’t climb, dig or collect; removing artifacts from state land is illegal.
Heat. The Santa Cruz Valley stays hot well into autumn. Carry water and plan for shade.
Archivist’s margin
Look at the press, then go read a territorial newspaper. The oddities in our files are what came out of machines like it.
