Near as I can figure it, through the possibly flawed perceptual filters of my own reality tunnel, the most likely answers this week, seem to me to be:
Q1. Dalbeattie
Q2. Southerness Lighthouse
Quite tricky this week, if you believe the clue about the lighthouse designer being born in 1854, then this places us at Helliar Holm, in Orkney which was according to some of the reference sources I checked, built by David Alan Stevenson c 1893. Helliar Holm however, does not fit in with the other clues in the puzzle and those seem to point to the location as being in Dumfries and Galloway and the thirty three acre 'Hestan Island' which has a solar powered lighthouse, with the originals being built c 1893 and c 1850. Couldn't find much information about an engineer born in 1854, who built the second one.
The Abbey is probably 'Dundrennan Abbey' which was built c 1142 by David I, who was a son of King Malcolm. It is thought that Mary Queen of Scots stopped here c 15th May 1568, on her way out of Scotland. A small town which lies to the north east of the abbey and which is famous for granite is likely to be 'Dalbeattie'. A king called 'John Balliol' (died c 1314) is thought in some quarters, to have been the owner of 'Buittle castle', which lies on the north western outskirts of Dalbeattie.
Driving south east from Dalbeattie, could bring us to Southerness and this dorpie has a disused lighthouse which was first constructed c 1748/49 and deactivated in the mid 1930s. Some of the reference sources I looked at claim that it is around thirty two feet high.
N.B. due to the number of people who normally write poison pen letters in green ink posting on his page, the Eastender has moved to moderated comments but rest assured, if you gave a comment or quip relating to the puzzle and its solution, he will endeavour to publish it.
