An interview with Dylan from Ffenestri Sgwar

English Translation

“A lot of people were complaining about the look of the high street – dog poo, chewing gum etc.

“I offered the pavement cleaners with the jetwasher. With the help of Councilor Rheinallt Puw, funding was received from the Lottery, World Heritage, and local people to carry out the work.

“I’ve been through it for three weeks, and hope to finish it today!

“Many people have praised the difference.

“With a bit of luck people will respect the street a little more.”
