On Steep Holm two jetties
were constructed, an iron one at the Landing Beach on the east coast and a
smaller stone one at South Landing.
Two batteries were
built on the top of the island. Steep Holm North was on the site of the
Victorian Summit Battery in the north west of the island and had clear views across
to Flat Holm and Lavernock Point on the Welsh coast. Steep Holm South was on the site of Garden Battery in the south east
of the island, which had views over the whole of Bridgwater Bay. Each battery
had two separate emplacements for 6 inch ex-Navy guns. The batteries were roofed with “plastic
armour”, which was a bituminous cement mixed with flint and granite chippings.

A rocket launcher
was constructed at Split Rock Battery. Observation posts were built at Rudder
Rock and Steep Holm South Batteries.

Two instrument pillars were built, one at each battery. Royal Artillery spotters mounted their Depression Range-Finders on them, which enabled them to observe targets and correct the fall of fire. They were surrounded by blast walls.

Up to 300 men were stationed on Steep Holm during the construction phase. Officers were housed in the Victorian barracks but lower ranks had to live in tents until Nissen huts were constructed.
Four searchlight
posts were built around the island: at South Landing; above Calf Rock;
above Rudder Rock and on the north coast to the north east of Steep Holm North
Battery. The purpose of these was to look out for German E-boats sailing up the
Bristol Channel. The top of the island
was too high to allow the searchlights to pan across the sea, so the
searchlight posts were built low on the cliffs.
Long flights of concrete steps had to be built to reach two of them. There were 120 steps leading down the Rudder
Rock searchlight post and 208 steps down to the post on the north coast. The
posts and the steps to them were painted with zebra camouflage to disguise
them. Two Generator houses were built to power the searchlights.

Two 3,200 gallon water tanks were erected on the top of the island, one for fresh water and one for salt water. Water was pumped up to the summit from a supply ship.
The refortification of Steep Holm was completed by October 1942. However the ex-Navy guns were never needed against enemy ships and they were useless against air attacks.
By the end of 1943 the threat to ships in the Bristol Channel had reduced significantly, so the island was relegated to “care and maintenance” status and most of the troops were moved off the island.
After the end of the Second World War German prisoners of war dismantled and removed most of the railway winches and trolleys and demolished the wartime piers.
