This church was founded in 1261. It is located within walking distance of Teatro Olimpico on Contra Santa Corona. It's altar is a completely intricate marble structure. The attraction is free.

2013 Update: The church has just been reopened after extended restoration. Truly surprizing why it is not listed among attractions in Vicenza, as the fine Bellini "Baptismal" is on display as well as superb high altar with its intricatly inlaid in marble scenes. I've added a few links below to the pictures for you preview.

It's amazing altar
