The Green Fort is a seventeenth century earthwork fortification in Sligo on the west coast of Ireland. The fort is an archaeological monument, and one with the highest level of legislative protection. Currently, a conservation plan is being developed to determine how best to protect, manage, interpret and present the site.green-fort-web-banner


The Green Fort is the largest and strongest of three spear-shaped bastion forts erected in the seventeenth century to protect Sligo town. These forts were the still-extant Green Fort and Coney Island Fort, and the now-lost Stone Fort which lay beneath Sligo Town Hall . The Green Fort appears to have had two or possibly three stages of development, and then passed into a long three hundred year period of abandonment. The site commands a view of Sligo town and the surrounding landscape and once defended the main route between south-western Ulster and northern Connacht.


The objectives of the Green Fort Conservation Plan are:

  • To assess the significance of the Green Fort and its significance as part of the surrounding environment.
  • To provide a framework to inform the future conservation and sustainable management of the Green Fort.
  • To present options for the future use of the Green Fort including partnership options for its future.
  • To provide the context through which the many different cultural values of the Green Fort and appropriate management can be discussed whether it be in terms of archaeology, architecture, military history (former battlefield), biodiversity, landscape, community, infrastructure, education, access, tourism etc.
  • Assist in the future development of appropriate interpretation at the site.
  • Provide guidance for a programme of regular maintenance.
  • Provide a framework, within which actioned progress for the long-term protection, conservation, management, interpretation and accessibility of the Green Fort, can be planned for and measured.
