Swansea's DVLA, Grand Theatre and Cardiff Castle were among the buildings which were lit up as part of the tribute to frontline health staff.
Thousands of people across the UK took part in the now weekly 'clap for carers' which takes place at every Thursday evening at 8.00pm.
Dozens of Welsh landmarks turned blue with images posted on Twitter and Facebook.
To honour our city’s amazing key workers and NHS staff, tonight at 8pm we will light up Cardiff Castle’s keep, City Hall, St David’s Hall and the Cardiff Bay Barrage sails to support the #ClapforCarers campaign. 👏💙 👏💙 #LightItBlue #WorkingforCardiff pic.twitter.com/fYZTRW5ibp— Cardiff Council (@cardiffcouncil) April 9, 2020
Even hospitals are now turning blue!
Residents in Foxhole Drive in Pennard showed their support by dancing in the street!
Wales manager Wayne Pivac released a video via the WRU Twitter account which featured his family taking part.
With the Easter weekend upon us, Welsh comedian Rob Brydon explains the importance of resisting the temptation to go out and about as the weather gets better.
And tots to teens take part in a new Welsh Government video too!

We know this isn't like any other holiday. We know it's hard to stay away from all of our friends and family. But please stay home this weekend.
