La Reunion de El Fuerte is a gathering of the descendants of the Mexican-American settlers of the Fort Lowell neighborhood (El Fuerte 1900-1960) who return for Mass at the San Pedro Chapel.

Fort Lowell Day begins at noon as a free public event and features artists and historic preservation with exhibits in Fort Lowell Park and a self guided walking tour of Old Fort Lowell.

The public event covers the 1000 years of history of habitation at the mouth of the Rillito including the Hohokam, Fort Lowell military presence, and the village of El Fuerte.
