Archeologists have begun work to investigate the land underneath Northampton's railway station.
The site is the location of the town's former castle which was ruined by Charles II before it was demolished by the Victorians, 133 years ago, to make way for the railway line.
The dig is happening in the front car park, ahead of the build of the town's new train station.
It's hoped that archeologists will uncover artefacts that tell some of Northampton's history.
It is causing some disruption to the station forecourt but the excavation site will be covered over soon. But, not before it has all been photographed, documented and the investigations are complete.
A contractor for the development of the new railway station is expected to be announced in December with the new station scheduled to be completed by March 2014.
