Second visit to this gem of a museum, first time since the opening of new gallery with loads of stuff relating to Stonehenge and the prehistoric landscape around it. Great fun day out, loads of activities for kids, and excellent gift shop too. Staff were really friendly and welcoming. Surprisingly good accessibility as well, especially for such an old building. Some nice tea-shops round the corner too.
All in all - strongly recommended, especially if you're planning to visit Stonehenge or Avebury.
