For the second year in a row, we asked people to light up buildings, monuments and their homes in blue to shine a light on Parkinson's.
With support from individuals and businesses, over 150 buildings across the UK lit up blue for Parkinson’s on the evening of World Parkinson's Day.
See where lit up blue near you on the map below.
What does it mean to see buildings in blue?
Karen lives in Scotland and she said:
"Seeing buildings lit up in blue is a wonderful symbol of unity and really shows the Parkinson's community in Scotland that we stand with them."
