On Google maps the spelling is Turlogh Parade rather than Turlough Parade and I could not find a street sign in order to confirm the spelling. I checked Apple Maps and the spelling is Turlough.
On arriving I asked a local the name of the park and she responded by telling me that it was the upper circle Marino. I later learned Marino has two large circular greens. Broadly speaking, each one is called The Circle but for the purpose of distinguishing between them there are various other names such as the Upper Circle [Croydon Gardens] and the Bottom Circle [Marino park].
I was unaware of this exact location until today [13 August 2022] even though I had heard of Croydon Park House.
The area where Croydon House once stood is now part of a suburb on the Northside of the city known as Marino.
Marino is approximately 15 minutes' drive from the National Library of Ireland. The Irish Citizen Army was founded in November 1913. New recruits were drilled at Croydon Park. Croydon House was demolished in the mid-1920s to make way for the Marino housing scheme. Several modern street names in the residential neighbourhood retain the Croydon name.
The townland of Marino was carved out of the townland of Donnycarney which was granted to the Corporation of Dublin following the dissolution of The Priory of All Hallows in the reign of King Henry VIII. In 1787, it was described by English writer Richard Lewis as "a small village a mile beyond Drumcondra and two-and-a-half miles from Dublin Castle."
The well-known Casino was built in 1759 as a summer house in the grounds of Marino House, demolished in the 1920s. A tunnel linking it to the main house for servants' use is where Michael Collins and his men carried out tests with their first Thompson sub-machine gun. The Asgard guns are believed to have been hidden here. The area was full of members of the Irish Citizens' Army. Jim Larkin lived in Croydon Park House and Countess Markiewicz and James Connolly were frequent visitors.
