The Espada Aqueduct, also part of the Park, is due west of Mission San Juan, across the river.

It is located upstream from Mission Concepción, in downtown San Antonio, and is owned by the State of Texas.

The Carl Levin and Howard P. "Buck" McKeon National Defense Authorization Act for Fiscal Year 2015 added 137 acres to the park.

In July 2015, the San Antonio Missions were added to the list of UNESCO World Heritage Sites.

In 2002, Archbishop Patrick Flores appointed Father Jim Rutkowski the archdiocesan administrator of Mission Concepcion.

In 2009-10 Las Misiones Foundation began an active, aggressive campaign to restore the interior of the Mission.

The Rancho de las Cabras, located about 22 miles southeast, is under the mission's jurisdiction and provided crops and livestock for it.

Visitors can experience the Missions by walking, bicycling,[9] or using San Antonio's new VIVA Culture bus routes.
