As we were expecting a wet afternoon we thought this would be a suitable location. It was brilliant, and surprisingly not very busy, although in fact it never did rain. So informative, and the information was put forward in so many different formats you were never bored. We paid £5 for the audio guide, which was well worth it. The whole complex of tunnels, which contains a series of galleries telling the story of German Occupation is very well presented. It must be great for families with children. The whole complex is on one level and is accessible to visitors with mobility problems. I used my own electric scooter throughout, but they also had scooters to borrow. The whole experience was very moving. Only down point was the lack of seating throughout for the able bodied.
