Thurrock Museum's logo is based on the 'Green Man' emblem to be found on a 13th. Century sculpture which decorates the top of a stone pillar with in Mucking church. The church is now redundant and in private ownership.
The Green Man, who is sometimes called Jack-in-the-Green, has a long history in traditional custom and art. The foliage that surrounds him shows that he is a spirit of the woods and he is particularly associated with growth and fertility.
