This is children's author, illustrator and farmer Beatrix Potter's house, which she bought in 1906 and where she wrote many of her tales. The house, along with a great deal of land in the Lake District, was left to the National Trust after Beatrix died in 1943. The house, which is 17th century, is really tiny and inevitably gets crowded - entry is often by timed ticket and queues are likely. However, you can also wander in the garden and see if you can spot Peter Rabbit.
You should also note that parking is very limited at this property.
