Hilton Palacio del Rio

The Hilton Palacio del Rio is a 485-room, 21-story hacienda-style hotel in San Antonio, Texas that opened in 1968.

The hotel was constructed for the 1968 World's Fair, HemisFair '68, and was designed by Cerna & Garza Architects.

The structure is notable for being a milestone in the use of Modular building construction techniques.

Modular units were built complete with plumbing fixtures, lighting, art work, furnishings and even ash trays.

The hotel features rich South Texas stylings and original art with the room interiors consisting of five different decor designs executed with custom built furniture by W.R. Dallas Furniture Studio, in San Antonio and rich fabrics in harmony with the overall theme of royal Spanish living.
