The Clock Tower is located at 1189 Washington Street, on the east side of Benicia, on a hill overlooking the Suisun Bay. It was originally an Arsenal storehouse. Constructed of sandstone quarried in Benicia, the original three-story building was finished in 1859. In old images of the building, it was strikingly reminiscent of European gothic castles standing guard river passages. It was a very imposing building perched above the waterway.

The third floor was considered extraordinary and ambitious in its day as it was suspended from great timber roof trusses by long iron rods. In 1912, a fire and explosion damaged the inner wooden frame and roof of the building. Only the outer walls of sandstone were salvaged while the roof and floors had to be rebuilt. It now has only two floors and is used for trade shows and other community events. This mural shows the two-storied Clock Tower as it was restored after the explosion. The horizon shows the Suisun Bay and the palomino hills of Contra Costa County.
