Boats passing through Athlone nowadays use a lock in the river, beside the weir and downstream of the current road bridge. Lock, weir and bridge were constructed by the Shannon navigation commissioners in the 1840s.
Before then, boats used a canal, about a mile and a half long, to the west of the river.
According to Ruth Delany’s The Shannon Navigation (Lilliput Press, Dublin 2008), the canal was built by Thomas Omer for the Commissioners of Inland Navigation. He started in 1757 and had over 300 men at work. He built a single lock 120′ X 19′ with a rise of 4.5′, but there was also a guard lock, further upstream, with a single set of gates to protect the canal against floods. There were two lay-bys (harbours), one above the lock and the other at the upstream end.
Although the old canal is no longer navigable, small boats are kept at its upper end and the entire line is easy to follow. The photos on this page were taken in March 2012; unfortunately the camera had an intermittent fault so some photos were not saved properly.
The map extracts are used by kind permission of Ordnance Survey Ireland. The coloured maps are from the survey of around 1840 (different sheets were surveyed and then printed at different times, so I refer to the survey as being ~1840) and the black and white are from the survey of ~1900.
Upper end to railway bridge
You can drive up quite close to the junction. The canal banks are neatly kept, presumably by the residents, and there are lake-boats tied to landing-stages in several places.

When the OSI map was drawn in around 1840, the Galway Road bridge and the railway bridge did not exist

Here are some links courtesy of the Athlone Live forum. Cllr Aengus O’Rourke set up the Athlone Canal Restoration Group (the link on that page isn’t working: I’ve asked whether there is a different URL). The group held a meeting in September 2011 and a walk, led by the learned Dr Harman Murtagh, in December 2011.
I am all in favour of linear recreational facilities — walking and cycling routes — along waterways, but I am generally opposed to restoring to navigable status, which (at least in Ireland) is rarely, if ever, a sensible allocation of resources.
Addendum
Isn’t this interesting? First, it shows that, although the canal was bypassed in the 1840s, it was not officially abandoned until 1982 (though I wonder when the lock gates fell down). Second, it suggests that Waterways Ireland (as successor to the Shannon Commissioners and the Commissioners of Public Works) still owns the canal, although I admit I’m making an assumption there. Third, it shows why Cllr Aengus O’Rourke said that Athlone Town Council would have to be involved in doing anything on the stretch from the Galway Road Bridge to the Battery Bridge: the town council seems to have leased that section, and the next as far as the lock, from the Commissioners of Public Works. I’m not clear about the role of Westmeath County Council and I’m assuming, open to correction by Athlone folk, that Heatons Mill Bridge was the bridge over the lock as shown on the ~1900 OSI map.

































Well done, Brian. I’ve walked the length a few times. Think the Urban District Council look after it. Hadn’t realised about the guard lock until you pointed it out. The southern area re-entering the river I found particularily impressive. Plenty of fishermen and boat activity when I was last there. Water level seems quite high when you took photo. Whole area far better defined in summer.
Thanks, Jim. I photographed the guard lock while wondering where the other set of gates had disappeared to, then found that (as always) Ruth Delany had the answer. bjg
Lovely piece Brian! Following representation from the Athlone Canal Restoration Group, Athlone Town Council agreed to commission a comprehensive feasibility study on the Canal with a view to exploring the possibilities for it from a recreational and tourism perspective. The report will be ready late Summer 2012. We (The Canal Restoration Group) will keep the pressure on the Council in order to have the most suitable recommendations from this report implemented. This will be a long, slow process but if done right it will benefit the Town for many generations to come. Our ultimate goal is to convert this redundant waterway into an attractive, high quality linear park with good walkways, seating, planting, landscaping, proper signage of areas of interest, proper lighting and have it registered as a national walk. I will keep you posted ! Best regards, Cllr Aengus O’Rourke, Athlone.
Hello, I have a marriage certificate for my ancestor Robert Butler in 1854, and his address was Canal Lodge, Athlone. Please have you any ideas where I could find out more about this ?
Thanks.
Canal Lodge is not shown on the OSI map from around 1840 [Historic 6"] but the words “Fountain/Canal Lodge” are on the version from around 1900 [Historic 25"]. I don’t know any more than that, but you might like to ask on the Athlone Live/Olde Athlone Forum, where there are some knowledgeable folks. The canal was out of use by 1854, so your ancestor might not have been working for the Shannon Navigation/Board of Public Works. bjg
Hi I would like Hazel Tapsell to contact me. Your Robert Butler is the brother to my John Butler who died in 1878 and is buried at the Cormanagh cemetery. There is also a sister named Dorothy. Their father is named John Butler too and when he died in1860 he was living at Canal Lodge in College Lane off Connaught Street Athlone. I live in Ipswich Queensland Australia, I have moore info about the this family of Butlers and I’m sure we could help each other. You are the only person in 20 years that I have found that is a cousin! Please write me, my email is ***************** [available via the site admin. bjg]
regards………….Geoff Butler
I have forwarded your email to Hazel Tapsell. bjg
I have now been in contact with Hazell Tapsell and we are cousins andcomparing notes. Further information is sought about Canal Lodge. My John Butler died there in 1860. Was the Canal Lodge linked to the Canal? (perhaps a residence for a manager or caretaker of the Canal?) When built and when demolished? I welcome your thoughts. My email is ********** [available to well-intentioned folk via the site admin. bjg]
