A gilt-framed picture of the Scrabo Tower, which seems to be a coloured-in wood engraving, is preserved at Mount Stewart. It gives an artist's view of the Londonderry Monument, showing three towers linked by two short stretches of crenellated wall. The middle tower resembles the one built. The others are much smaller. Wood engravings similar to this picture have been published in the Illustrated London News and the Dublin Builder. It seems that these pictures represent the original project before simplification to cut cost. Lynn's obituary in the Irish Builder attributes the design to Lynn.
