Extract from a Voyage of Inspection
10 th August 1818
Calf of Man
We landed and inspected the two Lighthouses now erecting at the Calf.By the contract ,the masons work of the towers was to have been finished by the first of the month-The Contractor,however,has not got the work so far advanced as he was bound in terms of his Contract to have done but he may have met with greater difficulties than what had been expected. At present the lower tower is built up to the cornice for the lantern,but there are about twenty foot of the higher tower still to be built. It is hoped,however,that the towers may be finished so that the lights may be exhibited in January next------------

By John Hellowell
States--"Point of Ayre lighthouse was completed on the 1st November 1818,

Also--"Eventually building of the lights got under way and a total of 300 men were employed on the Calf during the summer of 1818 for the task.Robert Stevenson was appointed the Engineer in charge of the task.
By August of that year construction of the lower tower was complete but for the lantern.The work was described by Steveson,when he paid a visit as being a credit to the inspector and contractors.The higher tower was a little behind schedule,but it was hoped to be completed in time for lighting by the end of the year.
----Eventually on the 1st February 1819, the two lights were illuminated for the first time....
