Castles in County Kerry: Ross, Listowel and Carrigafoyle

What this guide covers

This is a bounded guide to three state-guardianship sites with their own Heritage Ireland pages, not a ranking of every castle in Kerry and certainly not a claim that these are the only ones. Later country houses and privately held sites sit outside this scope, and nothing here should be read as describing access to them. Treat the three as documented examples you can research through the operator, and check each page for the season in which you plan to travel.

Ross Castle: Lough Leane setting and a legend

Ross Castle sits in an inlet of Lough Leane, and the official page says it is likely that the Irish chieftain O'Donoghue Mór built it in the fifteenth century. The same page also records a legend that O'Donoghue sleeps beneath the lake and rises on a white horse every seven years on the first morning of May, bringing good fortune to anyone who sees him. That is tradition, not documented history, and the distinction is worth keeping in mind when guides retell it.

Ross Castle history: the last Munster holdout

The same official page records that Ross was the last place in Munster to hold out against Cromwell. Its defenders, then led by Lord Muskerry, took confidence from a prophecy that the castle could only be taken by a ship, so the Cromwellian commander, General Ludlow, launched a large boat on the lake; when the defenders saw it, the surrender was hastened and the prophecy was fulfilled. That story belongs to Ross. The 1580 siege under Sir William Pelham, with its early use of artillery in Kerry, belongs instead to Carrigafoyle, and the two should not be blended together.

Ross Castle visiting: tours, capacity and season

The published 2026 season runs 5 March to 3 November, daily 09:30 to 17:00, with the first tour at 10:00 and the last at 16:55. Interior access is by guided tour only, on a first come, first served basis, and each tour is capped at 15 people, so arriving without a plan in high season is a gamble. The page does not publish online booking or tour frequency, so confirm the current position on the operator's page before you build a day around it.

Ross Castle access trade-offs

The page warns of challenging access for visitors with mobility issues because of a very steep incline, and it lists uneven walkways and a hand rail among the site's restrictions. It also notes that Ross is a very busy site and that summer visitors may experience delays, so a mid-morning arrival is more realistic than a late-afternoon one. Toilets are under the care of the National Park and include one disabled toilet; no other amenities should be assumed from the facilities list.

Listowel Castle: towers above the Feale

Listowel Castle stands on an elevation overlooking the River Feale, above the site of a strategic ford, and the operator describes it as one of Kerry's best examples of Anglo-Norman architecture despite only half the building surviving. Two of the original four square towers remain, each over 15 metres high, joined by a curtain wall of the same height and, unusually, linked by an arch on one side. Those details reward a slow look at the masonry rather than a quick photograph from the street.

Listowel Castle history: the 1600 siege

In 1600, during the Nine Years War, Listowel was the last bastion the Fitzmaurice rebels held against the forces of Queen Elizabeth, and its garrison withstood a siege for 28 days before Sir Charles Wilmot overpowered it. The page records that Wilmot then executed the soldiers left inside, a grim ending that helps explain why the surviving structure carries weight beyond its architecture. Read the site as a fragment of a much larger story rather than a complete medieval castle.

Listowel Castle status: closed for 2026

A dated notice on the official page states that Listowel Castle is closed for the 2026 season, with the intention of welcoming visitors again in 2027, and no exact 2027 reopening date is given. The published season of 30 April to 23 September 2026, daily 10:00 to 17:00 with last admission at 16:15, therefore applies to that season rather than to a visit now. For planning purposes, treat Listowel as one to check again rather than a stop to build into a 2026 itinerary.

When the site is operating, admission is free and access is by guided tour only, and the upper floors are reached by steep winding staircases with very limited wheelchair access. Those constraints matter for anyone comparing it with Ross: Listowel is the more demanding climb once you are inside, while Ross is the more demanding approach on foot. Both facts come from the operator's own pages rather than from a secondary roundup.

Carrigafoyle Castle: the Guardian of the Shannon

Carrigafoyle Castle is a late fifteenth-century tower-house built on a rocky outcrop at the mouth of the Shannon Estuary, a short distance from Ballylongford, and its name derives from the Irish for the rock of the hole. The operator says it was probably built in the 1490s by Connor Liath O'Connor and was known in English as the Guardian of the Shannon because it controlled shipping lanes to and from Limerick. At high tide a moat surrounded it, with a small dock beside the fortress where boats could moor. If the city's history draws you inland after the estuary, our Museums in Limerick guide covers its core collections.

Carrigafoyle history: the 1580 siege

During the Second Desmond Rebellion, the castle was garrisoned by fifty Irish rebels and sixteen Spanish allies under Captain Julian, and at Easter 1580 an English army under Sir William Pelham attacked it. The page recounts that the siege saw one of the first uses of artillery in Kerry and that the western wall collapsed under cannon fire on the second day, after which the survivors were put to death. News of the destruction spread quickly, and Askeaton Castle and Desmond Castle Newcastle West were abandoned shortly afterwards as the rebels turned to guerrilla warfare.

Carrigafoyle access: unguided and unconfirmed for 2026

Carrigafoyle is a National Monument in state guardianship and is described as an unguided site, with a caution that visitors should maintain care and caution throughout their visit. The caretaker internal-access notice on the page is dated to the 2025 season, from 9 May to 28 October 2025, so it does not confirm interior access for 2026 and should not be read as a current schedule. The tower-house is five storeys just over 24 metres high with a winding staircase of 104 steps, which matters only if internal access is available.

Choosing between the three

If you want a managed interior and a defined tour, Ross is the one with a published season and a documented tour system, at the cost of a steep approach and first come, first served places. If you want a free, guided monument when it is open, Listowel fits, but its own page says it is closed for 2026, so it is a future option rather than a current one. If you want an unguided estuary ruin and accept that interior access is unconfirmed, Carrigafoyle offers the most atmosphere with the least certainty.

Geographically the three sit in different parts of the county, with Ross near Killarney, Listowel in the north, and Carrigafoyle near Ballylongford on the estuary, so combining all three in one day is a question of driving rather than of castle-hopping on foot. This guide makes no claim about routes, distances or journey times; those belong to your own map and your own pace. For wider context on what else survives, see the collection of castle ruins in Ireland, and remember that ruins are often unguided sites with their own cautions.

Plan Around Access, Not Appearance

The useful decision for any trip built around castles in County Kerry is which of these three is actually open when you travel, because season dates and closures decide that before architecture does. Check the official Heritage Ireland page for each site before committing, and treat published dates as the operator's notice rather than a live guarantee. If your interests run to other periods and regions, Huntington Castle in County Carlow is a different kind of property with its own visitor arrangements.
