Tucson's Marist College, a historical landmark downtown.

The Marist College, which opened its doors in 1915, was in its first life a boys' school, in its second life Catholic Diocesan offices and is currently clinging to lif as its adobe walls deteriorate.

The building on South Church venue behind St. Augustine Cathedral was vacated in 2002 and five years later it was listed on Arizona's Most Endangered Places. It was nominated to the National Register of Historic Places in 2011.

"This remarkable building continues to be a beacon of Tucson potential," says Demion Clinco, president of the Tucson Historic Preservation Foundation.

Clinco says the building's Italianate and Spanish Colonial Revival style is impressive, and its location near the Tucson Convention Center is ideal for those who treasure what downtown Tucson has to offer.

"The elegant structure captures the industrious spirit of 1915 Arizona, a grand and early vision for Tucson's future," Clinco says.
