Slip No. 1 is one of two covered shipbuilding slips at Devonport South Yard, and is the oldest remaining covered slipway in any royal dockyard. Slip No.1 is sited adjacent to the dockyard wall and dates from around 1763 — its roof was added in around 1814.
The slipway is 53m long and the roof is supported by a double line of 23 trussed wooden pillars. At the north end, the roof is apsidal in order to accommodate the bowsprits of the boats — the pole projecting from the bow of a vessel that supports the foremast rigging.
The roof of Slip No.1 was designed by Mr Perring, Clerk of the Cheque at the Devonport Dockyard.
Although the slipway was relaid in 1914, it has undergone comparatively few alterations and is still used as was originally intended. It is now a Scheduled Ancient Monument.
