The Spanish Military Hospital Museum is located at 3 Aviles Street, St. Augustine, Florida.

During the British occupation of St. Augustine 1763-1783 a Scottish carpenter named William Watson purchased and remodeled the building into a dwelling.

These three parts plus their outbuildings and gardens functioned as a hospital complex during the Second Spanish Period.

A local coordinating committee, headed by Dr. James DeVito, was appointed and funds sought from the Medical Association's membership beginning in 1967.

The property was leased for commercial purposes until 1990, when the Historic St. Augustine Preservation Board reopened the museum on July 20 as part of the Restored San Agustín Antiguo living history program.
