The Castillo de San Marcos, as it's known today, claims the title of "oldest masonry fort" in the continental United States. The fort has changed hands many times in its centuries-old history; last used by the US Army, it was decommissioned in 1933, renamed a national monument, and turned over to the National Park Service. Our archival print celebrates the transition of the fort to a national monument and showcases early efforts by the Department of the Interior to promote interest in the beautiful site. Like all G.I. Prints products, this design is carefully handcrafted in the USA to an extraordinarily high level of quality and detail, and is suitable for gallery display and professional framing.

We produce all of our designs using only the finest archival-quality papers, inks, and dyes. We are 100% made in the USA using traditional, small-batch production techniques, with a focus on traditional craftsmanship and artistry.

Our papers are heavyweight, gallery-grade, and certified for environmental friendliness. Our inks are richly dyed and deeply hued, and will maintain their brilliance for decades.

The result of our relentless attention to detail and extremely high standards for excellence? An all-American, museum-grade product, suitable for framing, that you and your family can proudly display for years to come.
