The Omni La Mansión del Rio, originally home to the St. Mary's Institute, established on March 1, 1853, embodies this historical legacy. 1968, it transformed into "La Mansión," marking a significant milestone as San Antonio's inaugural luxury riverside hotel. Situated along the iconic River Walk, this historic hotel offers a gateway to the city's cherished past, including landmarks such as the Alamo, San Fernando Cathedral, and more. The hotel's blend of Spanish colonial architecture and European elegance provides a Four Diamond River Walk experience, making it an ideal starting point for exploring San Antonio's rich history and culture.
