Pitsea Hall, now called Cromwell Manor, sits next to the train line near Pitsea Train Station and gives its name to Pitsea Hall Lane, where the entrance to the hall is.
 
Pitsea Hall is mentioned in the Domesday Book but the current house dates from the 1600's. Other buildings that stood around the Hall were destroyed when the railway came to Pitsea in the 1850's. 
 
Grade II listed since 1950 the name 'Cromwell Manor' is taken from the Roundhead Military helmet which was found when the moat that sat in front of the Hall was drained.  Part of the moat still exists.
