Maynooth – castle keep, college cloisters and the Royal Canal

📍 Maynooth, Kildare

🏛️ Attraction

Last updated: 12 June 2026

The FitzGeralds made Maynooth their stronghold in the early 13th century, and the castle keep they began around 1200 – one of the largest medieval fortifications in Ireland – still commands the main street. Entry is free. The name is older again: Maigh Nuadhad, ‘plain of Nuadha’, after an ancient deity of sovereignty. These days the town, 24 km west of Dublin, runs on its university, which keeps the compact centre busier and better fed than most county Kildare towns of its size.

The castle and the Pound

Maynooth Castle
Maynooth Castle dominates the town centre.
Inside the keep, an exhibition covers the Fitzgeralds' turbulent run as Earls of Kildare and the growth of the town around them. The castle sits beside the [Lyreen River](/lyreen-river/), and a short walk away the Maynooth Pound – an 18th-century enclosure once used for stray animals – is now a small riverside park with paths and seating.

St Patrick’s College

St Patrick's College grounds
The historic grounds of St Patrick's College feature Gothic Revival architecture.
Founded in 1795 to train Catholic priests in the wake of the penal laws, the college later grew into the National University of Ireland, Maynooth. Its grounds are the architectural event of the town – neo-Gothic quadrangles by A.W.N. Pugin and James Joseph McCarthy, and a collegiate chapel holding a 3,106-pipe Ruffatti organ. If you only have an hour in Maynooth, take the guided tour here: it gets you the chapel, the 'Ghost Room' and an 800-year-old yew tied to the story of Silken Thomas. The campus Ecclesiastical Museum keeps scientific instruments, liturgical artefacts and manuscripts. Groups of ten or more must book ahead, and access for visitors with disabilities is limited – worth knowing before you arrive.

The Royal Canal Greenway

Royal Canal Greenway
The Royal Canal Greenway provides a flat, accessible route through County Kildare.
Maynooth is the eastern trailhead of the Royal Canal Greenway, a flat, fully paved towpath running over 130 km to County Longford. It starts near the railway station, suits wheelchairs and pushchairs, and takes dogs on leads. The first 20 km to Enfield – past old locks, woodland stretches and the Enfield Fairy Trail – is about two hours' easy cycling. Bring a layer: the canal-side breeze stays cool even in summer.

Carton House

Carton House
Carton House combines Georgian architecture with championship golf.
The former seat of the Dukes of Leinster is now a five-star hotel and golf estate, but its gardens, woodland trails and historic chapel stay open to the public, and the parkland fills with weekend walkers. The championship courses take bookings and host the Golfing Union of Ireland's national academy.

Eating and the market

The student population keeps the food varied. Avenue cooks modern Irish dishes with seasonal local ingredients, and Red Torch Ginger does Thai with a creative cocktail list; there are steaks and seafood at Stone Haven, Spanish and Latin American tapas at Picaderos. The Maynooth Market sells organic vegetables, handmade cheeses and baking in the town centre – Saturday morning has the widest spread, so do the market first and the castle after.

Getting there and around

Trains on the Dublin–Sligo line take about 40 minutes from Dublin Connolly, and the M4 serves the town by road. On-street parking in the centre is limited and timed; the larger pay-and-display car parks are by the university campuses and the Pound entrance. The castle and the Ecclesiastical Museum keep seasonal hours – typically daily from late spring to autumn – so check before travelling.

Further afield

Donadea Forest Park, about fifteen minutes west by car, has marked trails through mature woodland, a lake, a ruined castle and a café with a visitor centre. The Irish National Stud – guided tours of the stables, a museum of racing history and formal gardens – is at the far end of the county near Kildare town, around 40 minutes’ drive south-west.

Allow extra time for the college tour if you want to hear the organ – and book it ahead.
