Founder’s Day in St. Augustine

September 5, 2026

Come celebrate the 461st anniversary of the Ancient City’s founding.

It all started on September 8, 1565. Can you imagine what that day was like? What it was like when Don Pedro Menendez de Aviles set foot on this very spot and claimed Florida for Spain? The reaction of the native Timucuans? The celebration of the first Catholic Mass by Father Francisco Lopez de Mendoza? The first Thanksgiving meal in the New World?

With the help of dedicated historical reenactors whose members dress in full, traditional Spanish garb, visitors can experience that very special day, starting with the reenactment of the landing, complete with chalupa boats, as Menendez and his crew step foot on the grounds of the Mission Nombre de Dios. After the Mass held at the Rustic Altar, the celebration continues with a grand procession, cannon and musket salutes and a Thanksgiving meal on the grounds of the Fountain of Youth Archaeological Park, the site of the first Spanish settlement.
