Description
The Newbold Tunnel South Portal is a tunnel portal built between 1831 and 1834, with some minor alterations made in the 20th century. It is constructed of brick and stone and features a single, semi-circular arch with an upward curving band and a solid parapet. The spandrels curve outward and connect to wing walls that have trailing edges. The walls are primarily made of brick, except for the stone copings. Inside the tunnel, there are double towpaths with cast-iron handrails that have trailing edges for tow-ropes. This portal is a rare example of a canal tunnel with these features, which were part of the improvements to the Oxford Canal during the 1830s, overseen by consultant engineer William Cubitt. The North Portal is located in the civil parish of Harborough Magna.
