Antonine Wall and Forth & Clyde Canal

One of only six UNESCO World Heritage sites in Scotland, the Antonine Wall is very worthy of a visit, especially for a walk in the footsteps of Roman history.

There is enough of the earthen wall and ditch remaining to be able to understand its defensive qualities and to marvel at the a 37-mile wall built in just two years across Scotland almost 2000 years ago.

Roman soldiers built the Antonine Wall for the Emperor Antoninus Pius around AD 142.

Following the edge of a high ridge for much of the way, the views over Kilsyth and the Kelvin Valley, Campsie Fells and the Kilsyth Hills are equally impressive. Added to this, is a chance to spot wildlife on the Forth & Clyde Canal and wider Kelvin Valley.


Auchinstarry Marina

Home to barges and house-boats, the marina is great spot for observing life on the canal. OutdoorTrax at the marina also has a range of outdoor activities to try.

Forth and Clyde Canal

Engineer John Smeaton chose a similar route to the Antonine Wall for his canal linking the North Sea with the Firth of Clyde. Work began in 1768 and the waterway was opened in 1790.

Dumbreck Marsh

A designated site of Special Scientific Interest the marsh is home to many species of of birdlife, including lapwings, water rail and skylarks.

Croy Hill Roman Fort

Croy Hill was the site of one of the small forts built at intervals of one to two miles along the length of the wall. It is not visible on the ground today, but the Antonine Wall ditch is identifiable across much of the hill.

Castle Hill Iron Age fort

Now topped by a trig point, Castle Hill was constructed more than 2,000 years ago. It was thought to have been abandoned when the Romans arrived.

Barr Hill Fort and Roman Bath House

These are among the best Roman remains on the Antonine Wall. Enough of the floor of the bath house remains to understand how Roman central heating worked.

Silvanus, a Roman head sculpture

The new replica distance stone sits next to a towering Roman head sculpture at the Nethercroy Site, near Kilsyth, of the Antonine Wall. It is named after the Roman god of the woods, and sits at the Nethercroy site of the Antonine Wall.
