Lincoln Cathedral has switched on its new eco-friendly floodlights after nine months of darkness.
Engineers tested out all of the different colours available for the first time on Monday evening and it turned a lot of heads.
As previously reported, the old system which was installed in 1972 is being replaced with more than 500 LED lights.
It is expected to bring with it energy savings of about 80%.
When the system is fully up and running, the brighter white lights will highlight the Cathdreal’s intricate stonework.
In a bid to recognise important local, national and international events, the lights are also able to change colours.
It is being funded by the National Lottery Heritage Fund to improve the cathedral’s setting and visitor experience.
The Revd Canon John Patrick, Subdean of Lincoln, said: “Lincoln Cathedral is one of the UK’s most iconic landmarks.
“The cathedral is not only Lincoln’s brightest shining beacon, but possibly the most visible building in the UK at night.”
