The Sison Auditorium is a grand venue for events such as government meetings, international conventions, cultural shows, theater plays, graduations, and weddings, among others. It was built in 1926 simply as “Grand Provincial Auditorium” but it was eventually named after the late Governor Teofilo Sison, who was also the first Pangasinense to have become Secretary of National Defense. Its grand interior will leave visitors in awe.
