Thurrock Museum's logo is based on the 'Green Man' emblem to be found on a 13th century sculpture that decorates the top of a stone pillar 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 he is a spirit of the woods. He is particularly associated with growth and fertility.
