Iron Trunk Aqueduct

Highlight • Monument

Also known as Cosgrove aqueduct, the Iron Trunk Aqueduct was built in 1811 to carry the Grand Union Canal over the River Great Ouse. Two cast iron trough spans cross the river, held aloft by a single central masonry pier.

There is a wealth of excellent walking in the surrounding Ouse Valley Park, including two excellent nature reserves. A popular itinerary is to link the Iron Trunk with the village of Cosgrove, with a visit to the Barley Mow pub.

A delightfully charming and practical tunnel under the Grand Union Canal which is on an embankment along here. The tunnel was built just wide enough for horses to get through, which accounts for its distinctive shape.

A beautiful part of the wider Ouse Valley Park, Stony Stratford Nature Reserve is a great place to see breeding and over-wintering birds, as well as many dragonfly species.

Created in 1979 from the gravel workings used in the building of the nearby A5, the reserve comprises five lakes and 57 acres (23 ha) of wet meadow. It is owned and operated by the Parks Trust.

Two hides allow you to spot various bird species, depending on the time of year. Terns, oystercatchers and lapwings nest on the islands between March and June. It’s a good place to see a number of raptors, including kestrels, sparrow-hawks, buzzards and red kites. It is not uncommon to spot ospreys on autumn passage.
