Our team of guides and historians have been busy creating a new quiz for you this week, this time exploring your knowledge on the design of Tower Bridge. Take the Tower Bridge quiz below.
A huge thanks to Amy, Angel, Charlie, Daniele, Michael and Pierre, our fantastic guides who normally spend their time welcoming people inside Tower Bridge.
How did you do? Let us know by sharing your result on Facebook and Twitter and check back again next week for another Tower Bridge quiz.
