Sainte Élisabeth de Hongrie or Church of St. Elizabeth of Hungary is located at the heart of the historic Marais district, the Église Sainte-Élisabeth de Hongrie was built in 1646.

We weren't able to get inside of the church because it was close when we got there. The church is actually a walking distance from where we stayed in Paris.
According to my research, the church is rich in paintings and frescos from the mid-19th century, with a series of 100 carved wooden sculptures in bas-relief from the start of 17th century, as well as remarkable stain-glassed windows from the 1830's. The two organs are used to hold concerts.
