Station 3 — “Stonewall” — is one of Houston's original fire houses, built in 1903 with “Trust in Us” carved into the stone above the door. It ran on horse-drawn steamers until 1937, sat quiet for decades, and was restored in 2014. The fire pole is still there, along with the carved stonework and the old wood floors and ceilings.

Just outside downtown on Houston Avenue: exposed brick, high ceilings, and a courtyard. Two photographers, the whole day, on digital and 35mm film.
