The reason you might have spotted huge white words painted around Blackburn with Darwen this week People in Blackburn may be forgiven for thinking they ve been seeing things recently but they can rest assured their eyes are not playing tricks on them. For this week, huge white letters have been painted at various locations across the borough, as part of a new art installation for the National Festival of Making. The large words and poetry - celebrating spring, post-Covid hopes, and reflection - have formed the Of Earth And Sky – Open Air Poetry Experience and will be visible across Blackburn with Darwen from today until July 15.
