Remains of the old sea defences were uncovered under Clarence Pier Playing Field by contractors working on the new sea defence project in Southsea.

According to The Construction Index, the Archaeologist working on the project indicated that "the remains are highly likely to be those of the wider historic defences constructed as part of the 17th century remodeling of Portsmouth's earlier Tudor sea defences".

This is an exciting find, as it was thought that the previous system had been demolished.

GEOTEC Surveys have successfully detected former building lines on a number of sites over the years using Ground Penetrating Radar and other Geophysical techniques, which is completed without breaking the ground. An example of such results is shown below:

This data clearly shows the location of previous building lines and also provides a depth indication as to their positions.
