English: Minewatchers' Post. This structure, dating from the Second World War, was a minewatchers' post; during air raids, the personnel on duty here had to watch for mines that might be dropped by parachute into the River Clyde. Counting from east to west, it is the first of three such structures located on the shore between Bowling Outer Basin and the Erskine Bridge; for more information at Secret Scotland, see: http://www.secretscotland.org.uk/index.php/Secrets/ClydeMinewatchersPosts

The building is shown in context at 1481086. For the other two lookout posts, see https://www.geograph.org.uk/photo/1493370 (the second) and https://www.geograph.org.uk/photo/1493378 (the third). It is possible that there are others further upriver, but the shore there is occupied by various businesses, and is not readily accessible.

The structure was very cramped inside, with an internal height of about 1.8m; the internal space is about 1.7m square, but is further reduced by the fact that, at the right-hand side of the entrance, the outer wall turns and continues about halfway to the opposite wall, partially dividing the interior.

The brick walls are about 35cm thick, and the structure is topped with a concrete slab about 15cm high. The lookout slit itself can be seen to the right. Between the slit and the entrance, a much smaller hole is visible. This hole is inclined about 45 degrees from horizontal, and a portion of rusted pipe was still visible within it.

The second and third lookout buildings differ from the first, but are similar to each other; they both have two entrances (on the opposite side walls), and two shorter internal walls (one from beside each entrance); see the items on those buildings (links given above).

[It is perhaps worth noting that, in certain aspects of their construction, these lookout buildings are similar to one that stands beside the River Leven; this suggests that the latter structure, whatever its role may have been, dates from around the same time period: 1449321.]
