Poolbeg Chimneys

Overview

Rising 207 metres above Dublin Bay, the twin red‑and‑white Poolbeg Chimneys are the tallest structures in Ireland and one of the city’s most recognisable silhouettes. Built in two phases – the first in 1969 and the second in 1977 – they were part of the modern Poolbeg Power Station, colloquially known as Pigeon House. Though the plant was decommissioned in 2010, the chimneys remain standing, a testament to Dublin’s industrial past and a beloved landmark for generations of locals.

The chimneys are not open to the public; however, they can be admired from several scenic coastal routes, most notably Sandymount Strand, Irishtown Nature Park, and the South Wall pier. Their striking colour scheme and sheer height make them a popular photographic subject and a frequent backdrop in music videos, art prints, and graphic design.

Maritime Setting & Great South Wall Walk

The chimneys sit at the southern end of the historic Great South Wall, one of Europe’s longest sea walls. The wall terminates at Poolbeg Lighthouse, a red‑painted beacon first lit in 1768 and rebuilt in the 1820s. The walk from the Great South Wall car‑park (near Pigeon House Road) to the lighthouse is about 4 km one‑way (8 km round‑trip) and follows a flat, straight promenade that offers uninterrupted sea views and ever‑changing light on the towers.

How to get there

• By car – Free, on‑street parking is available near Pigeon House Road; spaces are limited and there are no dedicated paid car‑parks.
• By public transport – DART to Sandymount (≈10 min from Connolly) is the quickest rail option. Several Dublin Bus routes also serve the area: routes 1, 15A and 15B stop at Ringsend, a short walk from the wall’s start.
• By bike – Cyclists often park at the wall’s entrance and continue on foot.

The walk is popular with runners, photographers and anyone wanting a dramatic coastal perspective of Dublin’s skyline.

History

The story of Poolbeg begins long before the iconic towers. The original Pigeon House power station was erected on the site in 1903, after the area served as a military barracks. It supplied electricity to Dublin for much of the 20th century. The original plant was decommissioned in 1976, and the current station – built in phases throughout the 1960s and early 1970s – introduced the two towering chimneys that dominate the horizon today.

• 1969 – First chimney completed.
• 1977 – Twin chimney completed; both reach 207.8 m, making them the tallest chimneys in the Republic of Ireland.
• 2010 – Power station decommissioned; chimneys kept as a landmark.
• 2014 – ESU announced demolition plans; public outcry led to preservation.

Their red‑and‑white paint was intended to improve visibility for aircraft and ships navigating the busy harbour.

Recent Refurbishment (2024‑2025)

In July 2024 the ESB confirmed a multi‑million‑euro repainting programme. Work began with preparatory cleaning and the filling of roughly 7,000 holes per chimney. The upper sections are being painted in August‑September 2024, using about 90 tubs of red and 74 tubs of white paint, followed by a lower‑section repaint in spring 2025 and final completion expected summer 2025. Scottish contractors Zenith are carrying out the high‑altitude work, which also includes a new steel cap on each chimney to prevent water ingress.

The refurbishment is intended to give the towers a “new lease of life” for the next decades while preserving their iconic appearance on the Dublin skyline.

Energy Hub and Future Plans

Although the chimneys no longer emit smoke, the Poolbeg peninsula remains an active energy site. A gas‑fired turbine continues to operate alongside a large‑scale battery storage facility. ESB has announced plans to develop the area into a renewable‑energy hub, with future projects envisaging green‑hydrogen production and offshore‑wind integration as part of Ireland’s net‑zero target for 2040.

Recent statements from ESB executives highlight that the site now hosts:

• Battery storage capable of supporting half‑a‑million Dublin homes.
• Pilot green‑hydrogen electrolyser units.
• Offshore‑wind connection studies for the coming decade.

The chimneys themselves are not slated for commercial development, but the surrounding site is being consulted on possibilities such as a visitor platform, restaurant or other public‑amenity concepts. No concrete proposals have been approved yet.

Extreme Sports and Safety

In May 2024 a Red Bull‑sponsored wingsuit team flew between the two towers at sunrise, reaching speeds of 253 km/h. ESB described the stunt as a “serious safety incident”, noting that the chimneys are part of an operational site with ongoing maintenance work and that the team had not sought permission from the ESB. The Irish Aviation Authority and Health & Safety Authority were consulted after the event. While the stunt generated spectacular footage, the ESB reiterated that such activities are not permitted.

Structural Assessment & Future Outlook

A 2022 investigation commissioned by the ESB examined the foundations of the chimneys, which were originally designed for a 30‑40 year lifespan. Specialists sampled concrete and confirmed that the structural core remains sound, but recommended further monitoring and possible reinforcement to extend the towers’ life beyond 2030. Councilor Dermot Lacey has called for the chimneys to be added to Dublin City Council’s Record of Protected Structures, highlighting the need for a long‑term preservation strategy.

Cultural Impact & Media Appearances

The chimneys have transcended their industrial origins to become a cultural icon. In 1984, U2 filmed the video for “Pride (In the Name of Love)” against the looming towers, cementing their place in music history. An early press shot of Elvis Costello also features the chimneys shrouded in Dublin mist.

Artists continue to celebrate the structures. Fiona Snow’s acrylic model of the power station is sold at the Jam Art Factory, while graphic designer Fergus O’Neill’s “Pigeon House” print showcases the chimneys alongside a list of Dublin townlands.

What to See & Do

Viewing the Chimneys

• Sandymount Strand – A short DART ride from Dublin city centre brings you to this wide, sandy beach. From the northern end, the Poolbeg Lighthouse and the chimneys dominate the seascape. The beach’s flat expanse offers unobstructed views, especially at sunrise or sunset.
• Irishtown Nature Park – A pleasant walk through this coastal park provides a more natural setting. The park’s pathways lead close to the harbour wall, where the chimneys rise dramatically against the sky.
• South Wall Pier – Walking half‑way down the pier puts you at the water’s edge, with waves crashing on one side and the harbour on the other. Turn around and you’ll see both sides of Dublin – north and south – framed by the chimneys.
• Great South Wall Walk – Follow the 4 km stretch from the car‑park near Pigeon House Road to Poolbeg Lighthouse for a continuous view of the towers. Ideal for sunrise photography, jogging or a leisurely stroll.

Artistic Exploration

Visit the Jam Art Factory (online) to browse prints, laser‑cut models, and other memorabilia featuring the chimneys. The shop’s website showcases a range of designs, from minimalist silhouettes to detailed illustrations that incorporate Dublin’s historic townlands.

Nearby Attractions
