On an early visit to London I was quite amazed at the high cost of entering Westminster Abbey compared to the free entry to Westminster Cathedral. On looking it up I see that the Abbey is now £20 for a standard adult ticket while the Cathedral is still free apart from entry of £6 to the viewing gallery in the tower and there is a separate exhibition of treasures for which the cost is £5. At least it is free to just have a look round. Not sure what this tells us though.
