Strollers along the River Walk come upon a small stage on the north side of the river, with a little arched bridge and three Spanish-style mission bells in the arched limestone wall behind it. Directly across the green river on the south side sits a grass-covered amphitheater with seating that stair-steps up to the historic La Villita enclave. The hidden gem here is the picturesque Arneson River Theatre, created in 1939 by architect Robert Hugman as part of the Works Project Administration River Walk design. This unique theater is an informal, open-air venue, with tiered seating and good acoustics as sound crosses the river. During fall and winter, performance schedules tend to be inconsistent, covering everything from Tejano music to holiday choirs. By late spring and early summer, a solid schedule emerges. The Fandango folkloric troupe performs every Tuesday and Thursday in June and July, and the Fiesta Noche del Río takes the stage on Fridays and Saturdays from May through July. Often celebrating the Mexican heritage of old San Antonio, events at the Arneson are a delight. I've heard country music stars, seen a soap opera being filmed, and even celebrated Easter Sunday sunrise services. In 2013, visitors enjoyed an end-of-summer "throwback" movie series. You never know what you're going to see at the Arneson River Theatre.
