If you're ever in Reykjavík, check out the Hallgrímskirkja. Completed in 1986, located visibly, on a hill. From outside it's very impressive, with the soaring spire shaped (IMHO) like a supersonic aircraft ascending vertically. A stone angel. https://en.wikipedia.org/wiki/Hallgr%C3%ADmskirkja https://www.re.is/is/blog/guide-to-hallgrimskirkja-church-re... https://yourfriendinreykjavik.com/hallgrimskirkja-a-tribute-..…
Also, don't miss out on the botanical garden and its café, it's right around the corner!
