The beach of Benone stretch from below Mussedun Temple at Downhill to Magilligan Point, a distance of several miles and is one of the longest beaches in Ireland, excellent for walking. A car ferry service crosees regularily across to Greencastle in the Republic of Ireland. To see Magilligan from above, a trip to Gortmore viewpoint on the Binevenagh Scenic Drive is recommended. The views from there and also Binevenagh Lake on the plateau are truly breathtaking.
At Magilligan Point there is a classic example of a Martello Tower which is matched by an identical one at Greencastle, they were built in 1812 during the Napoleonic Wars to guard the entrance to Londonderry against any possible invasion. The inspiration for these unique structures trace back to an encounter the Royal Navy had at Mortella Point in Corsica in 1794 where they tried unsuccessfully to take one with two naval ships. The shape and thickness made them resistant to cannon balls and with a mounted cannon on the flat roof which could fire in any direction they proved a very tough defence.
Magilligan was also used as the baseline during the first large scale mapping of Ireland by the Ordnance Survey in 1827, the baseline was eight miles long and passed through three fixed circular triangulation stations which are still intacted today. The work carried out by Major General Thomas Colby achieved the highest level of accuracy at the time, in comparison, it was remeasured in 1960 using electronic equipment and the new measurements differed by only 1 inch from those of 1827.
