Trinity Bridge is a genuine curiosity — a three-armed stone bridge, built in the 14th century, that now stands high and dry in the middle of Crowland with no water beneath it. It once carried three ways over the meeting of the Welland and a tributary; the rivers were later diverted and left the bridge stranded among the streets. It’s the only bridge of its kind in Britain, a short walk from the ruined abbey, and worth pairing with the rest of Crowland.
