But I have not yet so thank you for sharing

Glad you enjoyed the pictures. Brutalism is a love hate design. My wife really hated it the first day. But seeing it in the sun softened her view a little. Plus the inside is better with sunlight since the glass area is small.

The outside light makes a difference in tone.

One of the stops on our cruise is Le Havre. We're doing a shore excursion to Rouen, but I hope to have time to walk around Le Havre afterwards.

Don't know where cruise ships moore. You might want a taxi. The town was largely destroyed during the war so you don't get it that quaint vibe.

Very cool place. Those two pics remind me of something out of battlestar galactica or star wars where you'd see spaceships taking off or coming in for a landing.

Doesn't it.
I like that you get to see the bones of the structure. With little jewels attached.

The new cross is "a modern industrial-style metal sculpture ... constructed from weathered, rusted steel pieces, including what appear to be bent nails or bar stock."

It isn't especially large. Understated and I think fits well on the church.
