We didn't have time to go through the tower to see...

We didn't have time to go through the tower to see the Jewel amongst other historical artefacts but looking at the building itself was quite impressive. The tower is quite large and located beside the iconic Tower Bridge so it is fairly easy to find. The masonry and stonework visible from the outside was enough to get me excited about going in.
We were told you would need about 1.5-2 hours to go through the tower when booking tickets which was why we didn't end up going in since we would have only had an hour. It was nice that they weren't all about just selling tickets. We went to get tickets at the kiosk but think you were also able to do it online.
It was disappointing we didn't get to go in but it is now on the list for the next visit.
