Welcome to Radius -

Radius invites visitors to explore and enjoy art, music, movies and delicious desserts. The ongoing art exhibits, and fresh menu selections in the cafe are just part of the backdrop provided for our meetings, concerts, banquets, etc. Surrounded by history and architecture downtown on the Auditorium Circle, Radius houses a community of art- and education- oriented nonprofit organizations inspiring the community through furtherance of their missions. In addition to the cost savings and synergy resulting from the cooperative, Radius generates engaging programs and a wide range of activities, including book signings, art exhibitions, and discussion groups. Radius seeks to provide free access to the arts in an inviting contemporary setting to entertain and engage the community.

The historic buildings that share the Circle include AT&T, the Toltec Apartments, and the Municipal Auditorium which is soon to be the Performing Arts Center and a stop on the northern extension of the San Antonio Riverwalk.

Part of the Radius Mission is to provide communal space where nonprofit organizations are better able to fulfill their missions and where individuals are inspired to dream and to do. Any group is encouraged to contact the Radius office concerning building usage to accommodate the group's mission and needs.

Office hours are 8:30AM to 4:30PM and scheduled evenings.
