A Canal ran through it.

The old canal bed can still be seen in Glynneath

•The Neath canal is 13.5 miles in length from Giants Grave to the Terminal Basin at Glynneath.

•In this talk we will look at the section through Glynneath with a few pictures of now and then.

•The following are distances between locks on the Neath Canal at Glynneath.

•Chain Road Lock      No. 16                        0.4 miles  

•Pentremalwed Lock (Fox’s Lock) No, 17 0.24 miles    

• Lamb and Flag Lock        No. 18               0.17 miles    

•Maesmarchog Lock          No.19             0.25 miles    

•Terminal Basin Glynneath               0.3 miles

The last locks on this stretch of canal have mostly gone but you can still see where they were.

•The Neath Canal has been a major feature of the Neath valley since opening in 1795.

A little bit of history 1795 – 1934

•Traffic on the Neath Canal increased from 1799 and reached an annual tonnage of 200,000 tons in the mid 1820’s and continued at this level up to the 1870‘s

•But there was now competition from the Vale of Neath Railway.

1795 – 1934

Most of the collieries in the Neath Valley transferred over to the railway and the canal fell into decline

    By the start of the First World War, traffic had virtually ceased.

   After the war, traffic was almost non-existent,

   The last toll was taken in 1934.

I am going to use maps to illustrate the route then and now

•So our journey begins by the Aberpergwm Pit and the Chain Road lock.

Lock 16 looks in remarkably good condition but it is difficult to access – picture taken August 2022

From Lock 16 we can follow the canal bed to Pentremalwed Lock (Fox’s Lock) – I am sure you all recognise this gateway  to St Cadoc’s:

Today there is little left of lock 17 but the canal bed still leads towards ‘The Lamb and Flag’

And this is where we can see how much has changed – compare with the 1970ish view.

This image shows a functioning lock today this is buried.

Now it has gone – but we can walk on.

A little further along the remains of the canal bed continue to Maesmarchog Lock No 19

Today there is little to see but we have a very good photo from back in the day

We can follow the bed of the canal a little further but the final part now lies under the A465.
Some intriguing clues remain for those who do not know the history,
For example the ‘Canal Cottages’ with no canal in sight !

Our merged maps show where the wharf was located.
