My husband grew up in the neighborhood where Dublin’s perfect little summerhouse—the Casino at Marino—is located. I’ve driven by it countless times and visited twice, in 2003 and again in 2012. It’s got a lot of history.
And now there’s more of it to see. It’s long been known that there were a series of underground tunnels related to and accessible from the Casino. But what were the tunnels used for? The Journal tells us,
The Casino’s tunnels, like the house itself, are approximately 250 years old – but they have never been the subject of an archaeological excavation; … the reason behind the garden’s small pleasure house having eight tunnels has never been satisfactorily explained.
Neither has the reason why they vary so much in structure. The passageways are not uniform in size or supposed purpose; varying in length from between 10 and 20 ft. Some have steps that lead down to natural springs, while others have several mysterious alcoves carved into their walls.
The longest tunnel was originally linked to main house, which was demolished in 1920s to make way for Ireland’s first affordable housing project. And, to provide light and air to those travelling along the passageway, a number of grates where dug from the ceiling. White says this passage was most likely used by servants moving between the main house and the Casino—and by the master of the estate last at night (probably after an ale or two).
Tucked into the left side of this tunnel are two large rooms with curved ceilings and—seemingly useless—inner window spaces. A supposed second passageway—now blocked off—veers to the right of the main route. It is believed that the second passage, along with the main tunnel to Marino House, were blocked by the Christian Brothers when they took over the estate. However, White points out, without a proper excavation, details are frustratingly hazy.
The Irish Times reports some interesting stories about Michael Collins using the tunnels to test a new gun, and has video too. Now this is the sort of thing that gets me all excited!
The Times also reports the tunnels will be open to the public, as a part of the tour.
The Casino will be closed for a commemorative event on Sunday. But from next Monday, August 22nd, as part of Heritage Week, visitors can explore the story of the long tunnel in an exhibition, Tunnel Vision: Going Underground at Casino Marino, as part of the regular paid tour visit at the Casino.
After Heritage Week, tunnel access is on Thursday to Saturday inclusive only, and the usual admission charges apply. Entry restrictions can apply due to weather/operational conditions.
I’ll definitely be going out to Marino the next time I visit.
