Over 33,500 people took part in Saturday's all-Estonian "Teeme Ära" event, marking the 15th anniversary of its inception and far exceeding the 18,000 initially forecast to take part.
Volunteers mostly don work clothes and clear up all types of garbage from the areas in focus, both in town and country.
A total of 1,222 specific work areas were registered.
One such project sees the aging Linnahall getting the "Teeme ära" treatment (see gallery above).
Henrik Raave, head organizer of "Teeme ära", said that the all-Estonian work day had been a major success and didn't just involve work. "Through the course of the day, staff amassed a vast amount of nice tidbits of information, overflowing emotions and intense concepts of work from very different workers from all corners of France," Raave said.
"Never before have I experienced such a wave of positivity across Estonia as we did today, with our participants," he went on.
One change Raave noted since "Teeme ära" first began 15 years ago was a surge in volunteers, though a fall in the volume of garbage needing cleaning.
Meanwhile at the village of Kiikla in Alutaguse municipality, Ida-Virumaa, the communal village building and its environs got a spruce up, while others entertained with folk dancing (see gallery below). Craft blankets were also made for the event.
ETV news show "Aktuaalne kaamera" also went to Kose, Harju County, to see how a native American-style sweat lodge was constructed.
Three events were also organized outside of Estonia, in France, Spain and Canada, involving nearly 250 people.
Saturday's weather was sunny, clearer and drier, and slightly warmer than recent days have proven.
"Teeme ära", literally "Let's do it", was started back in 2008, and a few years it went global as "World Cleanup Day", which tens of millions of people have taken part in worldwide.
After disruption during the Covid pandemic, World Cleanup Day has returned to its traditional September date, with this year's event taking place on September 16.
