The streets of Cardiff were empty and deserted as 2020 came to an end.
The welcoming of a new year usually means huge crowds and packed bars and clubs in the Welsh capital.
But Level 4 restrictions mean that all non-essential outlets are closed, and people listened to the message to stay at home.
The streets were like a ghost town with only a small police presence.
The shutters were down as pubs and clubs that would normally be packed to welcome in the new year remained closed.
It was all very different to how it has looked on previous New Year's Eve nights in the city centre. These pictures are from 2016 and 2020 as the new decade was welcomed in.
New Year's Eve was also "quite quiet" in London, where Tier 4 restrictions meant that most places were closed.
Ken Marsh, chairman of the Metropolitan Police Federation, said sporadic gatherings of people in London "who just won't take note of what is being said" were quickly dealt with by officers and smaller gatherings were also dispersed.
He told BBC Breakfast: "I think the public have really cottoned on that this is really serious, the position that we are in, and we did not see the numbers we thought we would."
Princes Street Gardens in Edinburgh, where live music and a Christmas Market usually attract thousands of people from across the UK, were almost completely desolate this time round.
Scots were told to celebrate at home, with Edinburgh's traditional Hogmanay street parties were replaced with "drone swarm" videos shown on TV.
They featured a swarm of 150 illuminated drones which form symbols and animals in a "beautiful ode to Scotland" over famous landmarks.
Elsewhere in the world, New York marked the start of 2021 with its famous Times Square ball drop but it was largely closed off to the public with Americans instead forced to watch via live-streams.
The same place that last year saw over a million people pack in to watch the annual tradition as well as live music performances was far more sombre.
