Marsh House dates back to the early 1800s where it was once the family home of the O'Malley who were agents of landlord, Lord Lucan.
Until recently the house was the municipal headquarters of Castlebar Urban Council. With the abolition of the urban districts in 2014, the council moved out and it has now been given a new lease of life and houses the Castlebar Educate Together primary school.
Before the council took it over sometime in the 1970s, it was occupied by Ms. Madge Feeny who was daughter of a local businessman, Mr. Patrick J Feeney. After her death, it lay vacant for some years, and on September 19th, 1979, Lauretta Feeney Biggeln travelled from the USA to unveil a plaque on the wall of the building. Lauretta was a descendant of the family and the plaque reads:
"To the memory of Patrick J and Sara Feeney and their children, Hubert, May, Nellie and Madge.”
The town river runs alongside the lawn of the house and often turf, animals, and farm produce was brought by water to Castlebar for sale in the nearby market square. There was a landing stage there where the lawn is now and this played an important role in the commercial life of the town. With the development of the roads, this practice discontinued.
The Greenway now runs through the grounds going from Lough Lannagh to the Museum of Country Life, Turlough.
