The Watts Towers were created by artist Sabato Rodia. The Watts Towers Common Ground Initiative supports the towers as a cultural landmark. They are honoring the towers and the initiative with a festival: The St. Joseph's Communal Tables on March 18-20. "These tables both commemorate a time when diaspora Italians represented a community in need, and, as a springtime recurrence, they also celebrate abundance." Luisa del Guidice is organizing the event. More about the Catholic tradition of St. Joseph's tables here.
You can view the altar at St. Lawrence of Brindisi Church (10122 Compton Ave., LA): Friday March 18, 3:00 P.M. – 7:30 pm, Saturday March 19, 10:00 A.M. – 5:00pm, Sunday March 20, 10:00 A.M. – 5:00 pm.
