RAF St. Lawrence was located on the coast about two miles west of Ventnor. It was initially established as a 'Remote Reserve' for the Southbourne site (on the mainland at Bournemouth) and first became operational with mobile equipment in 1941. However, when the buried installation was constructed it was obvious that it had a dual function as an Emergency Alternative Reserve for RAF Ventnor. This was because the Buried Reserve constructed at the St.Boniface site was considered vulnerable in the event of another air-raid attack there. In use, unlike Ventnor, the site was found to have an excellent height finding capability, being situated only 44 feet above sea level and because of this it took on 24 hour working. Accommodation for personnel was in local hotels. Line of shoot was 170 degrees, i.e. 22 degrees more southerly than Ventnor's, so the coverage would not have been exactly the same and the range would have been shorter too. The two towers were of wood and were 105 feet high. The site continued in use until 1947.
A plaque of commemoration was unveiled on April 10th.1994 at the Old Park Hotel by Lady Barclay and Sir Peter Anson as part of a weekend reunion held there.
And sixty three years later, this is what it looks like today:-


The transmitter dome is equipped with an elaborate feeder portal.
Or from the air this Google Earth extract gives a perfect impression of the site layout.
There is an additional bunker and other huts in the trees close by.


The Officers' Mess was in the nearby Old Park Hotel shown below and the other ranks were accommodated in the Rocklands and Whitecliffe hotels.
The bunker and huts photographs taken & kindly supplied to be displayed here by 'Barrie H', another Island resident.
