My family and I will be visiting London this summer and I'd like to get some suggestions of things to see that might not make the standard tour guide. What I'm especially interested in would be things/places of Christian historical importance. So, for example, Bunhill Fields Burial Ground. Also, I'm planing on going to the British Museum, but want to make sure I don't miss something of significance among all the other exhibits. Any suggestions would be appreciated. Day trips are OK, too, if we can go by train. This will be our first trip to Europe. Thanks!
