Ballyhaise House, situated on the Annalee river, was built for the Newburghs, a local landowning family, in the 1730s. It is said to contain the earliest surviving oval room in Ireland and Britain. The building was traditionally credited to Richard Cassels, a German architect living in Dublin, who designed many of the capital's finest buildings and squares. It is more recently thought that Ballyhaise house is actually by the architect of the Irish Houses of Parliament in Dublin, Sir Edward Lovett Pearce. Ballyhaise House has been used as a Teagasc agricultural college since the beginning of the 20th century; celebrating its centenary in 2006. The bridge near the house is reputed to be nearly 300 years old. Ballyhaise Market House is a five bay, two-storey building.
