Deceiving exterior

I think we all hear all the time, that we shouldn't judge thinks from the look of them.

And it describes this cathedral just perfectly.

The place Ireland, Galway city, on the west coast. The full name of the cathedral: Cathedral of Our Lady Assumed into Heaven and St.Nicholas. From outside, the cathedral itself doesn't look great, and nothing would suggest that inside is different. But once in, you see it in an instant. We were visiting on a sunny day, so the lights were perfect. So many beautiful painted lead-glass windows, I was really glad we didn't get deceived by the outside look. A lesson to remember.
