Old Town San Diego State Historic Park presents the opportunity to experience the history of early San Diego by providing a connection to the past. Old Town became a state historic park in 1968, when work began to restore and stabilize its buildings, particularly the original adobes. Five of these have been restored: La Casa de Estudillo, La Casa de Machado y Stewart, La Casa de Machado y Silvas, the Pedrorena-Altamirano House, and La Casa de Bandini, which became Albert Seeley's Cosmopolitan Hotel. Two other buildings—The Schoolhouse and San Diego Union Building—have been restored as 19th century buildings typical of early American wood-framing practices. Seeley Stable, Robinson-Rose Visitor Information Center, Colorado house, the First San Diego Courthouse, and La Casa de Rodriguez have been reconstructed.
