Telford's Tower (1957, listed Grade II 1971) was built to mark Thomas Telford's bi-centenary. It is an "L" shaped stucco building with an oriel window at its base and a shingle roof with vase finial. Its interiors are finely detailed. A concrete spiral staircase leads up to tower bedrooms. It is a self-catering cottage for three (double and single bedroom, sitting room, kitchen/dining room, bathroom). Between Telford and Unicorn a flight of steps leads through an arch embellished with a high relief lion and unicorn coat of arms to an empty space where Clough had proposed to site his final building at Portmeirion, to be called The Lion Tower. He said in an interview with Peter Davey (11 February 1973), "There is just one tower I want to add between Telford's Tower and the Unicorn."
