Curdworth, a small village in North Warwickshire, has the Birmingham & Fazeley Canal run by it. Part of the canal (just over 50m of it) runs underground through the Curdworth Tunnel. The tunnel is about 120m north east of the centre of the village and was built along with the rest of the canal in the late 18th century, being a fairly early canal tunnel.
The tunnel has a towpath running alongside the canal as well as brick ridges which originally would have been to help prevent horses slipping while pulling the canal barges. Curdworth itself dates from the 6th century and was originally settled by Anglians. Despite being only 8 miles from Birmingham and lying near to the motorway (and one day HS2) the village retains its rural charm.
