My son is in town for a few days, so pretty much at the top of our to-do list was a trip to London's Natural History Museum.

It's great to know that these fantastic spaces are basically still free to visit.

The museum is a very busy place.

The main entrance hall.

The main reason for me to go this time was to take my son. He was armed with a loan-phone, so took pictures of his own.

Below is his story of the day. It starts out in the Saatchi Gallery which we stopped off in for a short while before heading to the Natural History Museum.
