Is this 'tower' looking out to sea, and part of a larger building like a former hotel?
The arches to the bridge at Bridge can't be seen from road level as the road was widened by extending beyond the former bridge parapets. However, when the stream is dry it is possible to walk along the stream bed from the Mill Lane ford or from Riverside Close and look under the later bridge widening, where it is possible to see the double brick arches of the eighteenth century bridge.
