Nottinghamshire is famous for its involvement with the legend of Robin Hood. This is also the reason for the numbers of tourists who visit places like Sherwood Forest, City of Nottingham, and the surrounding villages in Sherwood Forest. To reinforce the Robin Hood connection, the University of Nottingham in 2010 has begun the Nottingham Caves Survey, with the goal "to increase the tourist potential of these sites". The project "will use a 3D laser scanner to produce a three dimensional record of more than 450 sandstone caves around Nottingham".
