Since the colonial era, domestic chapels were often part of a home’s architectural layout. Even into the early 20th century, architects like Refugio Reyes continued the tradition of incorporating these intimate spaces for prayer and reflection in the homes they designed—such as the one that now houses the Regional History Museum of Aguascalientes. This gallery, dedicated to devotional objects, includes liturgical artifacts, religious garments, ex-votos, viceregal paintings, and ecclesiastical furniture. These pieces date from the late 17th century to the early 20th century. This gallery also houses the original altarpiece designed by Refugio Reyes specifically for this space.
