The Lower Lighthouse is one of a pair of lighthouses built in 1818 on the Calf of Man, the small island off the Isle of Man's south-western tip, under the Isle of Man and Calf of Man Lighthouses Act 1815. It was designed by the noted Scottish lighthouse engineer Robert Stevenson to warn shipping of the Chicken Rock reef lying off the Calf's southern end. Together with its twin, the Upper Lighthouse, it guided mariners for over half a century until 1875, when both were superseded by a single new lighthouse built directly on Chicken Rock itself, better placed to warn ships in foggy conditions. The two early Calf lighthouses have been disused as navigational aids ever since, though they survive as among the oldest lighthouse structures associated with the Isle of Man.

Lighthouse. This lighthouse, together with its twin nearby, was built in 1818 for the Northern Lighthouse Board to the designs of Robert Stevenson, one of the Board's most famous engineers. The two lighthouses worked in tandem, indicating to passing ships if they were in danger of colliding with the Chicken Rock nearly 2km to the south. The Stevenson lighthouses were replaced by a lighthouse on the Chicken Rock itself in 1875, after several difficult years of construction. More recently a modern light, warning of the dangers of the Calf of Man itself rather than the sinister reef to the south, was installed close to the old Stevenson towers in 1967, but this was decommissioned in 2007 as unnecessary in the modern age of satellite-enabled navigation and global positioning. The Chicken light was upgraded at the same time so that its light is visible from a distance of 21 miles. In common with many of the NLB's installations, each lighthouse was attached to a keeper's house, with adjoining garden and other basic facilities. The buildings are now maintained as nesting sites for birdlife in keeping with the status of the Calf of Man as a nature reserve and bird observatory.

"Round Ellan" or "Loyal Fort" is a circular earthwork of unknown purpose and date. It is visible on modern aerial photographs and the present field boundaries respect its present, curving around the outside of its western and southern sides. A rim sherd of poorly glazed micaceous ware, considered to be 'medieval' as been found just inside east margin of the plateau surrounded by the earthwork and are now kept at the Manx Museum (Accession No. 1967-0125). Stone cists have been reported in the past as being uncovered whilst digging drainage trenches in the field to the east of the enclosure. The authorities given for this information were the Venerable Archdeacon J.C. Moore. M.A., Mr F. Ratcliffe, and Mr D. Quirk, Kirk Andreas.
