Little Turtle was blown away by the mosaics and stained glass in La Basilique du Sacr̩ Couer de Montmartre. It was truly worth the wait Рthe first stone was laid in 1875 and the building was only ready for consecration in 1914! In particular, the mosaics took 22 years to install, and the stained glass windows took 17 years to fit (and had to be replaced when they were destroyed by bombing in WWII).
