Tufa has been used in buildings since early medieval times and there are plenty of examples close to home. Still in situ on Saint Patrick’s Island are the remains of vaults and windows built out of tufa; the medieval church of Kenure and several wells on the local beaches also feature tufa. And why not? There are tufa sources in the form of petrifying springs all along our coast from Barnageeragh to Drumanagh to Rush. What is tufa and why was it favoured as a building material? Find out at Niall’s talk on 13th November.
