The Calon Lân Project originated as an idea from a renewed interest in Mynyddbach Chapel and its rich heritage. In 2011 the chapel was on the point of dereliction but through the combined efforts of Reverend Grenville Fisher, Roy Church and the support of Treboeth Historical Association the building was saved. A project was set up to encourage and maintain an understanding of local heritage and to establish collaboration with other local organisations.
Mynyddbach has a rich cultural heritage and is the burial place of Daniel James who had the Bardic name of Gwyrosydd. Daniel wrote the words of the famous Welsh Hymn Calon Lân.
The Trustees, members and friends of the chapel are in the process of establishing the Calon Lân Heritage Centre. Through the work of the project the buildings and grounds at Mynyddbach will be preserved for future generations. The project aims is to give communities a sense of belonging and identity by using the history of the local area and the story of Calon Lân. The people of Swansea and beyond will have a better understanding of their cultural heritage and the many historical links to the past.
