One of the largest buildings you can see from Centre Pompidou is the church of St. Eustache.  The building actually dates back to the 13th century.  The current church, a gothic masterpiece, was built between 1532 and 1632. St. Eustache was prominent enough in Paris to have Louis XIV take his first communion there and Mozart has chosen this church as the location for this mother funeral.  Today, we were treated to a choir performance which filled the church with beautiful voices, it was quite moving actually.
