Royal Alexandra Theatre
The theatre was built in 1907 and continues to operate to the present. It was named after Queen Alexandra who was the wife of King Edward VII; she is also the great grandmother of Queen Elizabeth II.
It has so many lights that it lit up a good portion of the street in front of it. I've only been in there once and that was to watch Mamma Mia the musical; great show... much better than the movie.
