The early building on the site dated from the 13th Century, but the later dwelling at Ashford Castle, which can be seen in the sketch above, closely resembled a french chateau. It can still be seen if you look closely from the lake, with all the additions to the "Castle" crowding around it as it sits in the centre of the structure.
There is also a very interesting shaped jetty to the west of the boathouse. shaped as such to allow easy access to seaplanes.
