On the 17th April the Channel 4 series, Wreck Detectives, will air a programme filmed in Guernsey, and under the water in St Peter Port harbour, investigating the five Medieval wrecks which are located there.
The idea is the try and understand why they are all grouped together like they are and why they appear to have all sunk at around the same time.
Production company RDF Media are responsible for the series and worked on the initial planning of the shoot with the Guernsey Film Commission.
