One of the most impressive sights on this trip to London was Westminster abbey. It’s a bit morbid, filled with tombs of dead royalty and famous Brits with lots of memorials to others. The audio guide is good and full of information. Everyone shuffles through at the same pace, and some of the small chapels get pretty crowded.
Photography isn’t allowed inside, so I didn’t get any photos of the beautiful stained glass. I did get a few of the ceiling before I realised this. Oops.
