The collection of about 200 modest homes on a hillside above a river used to be a typical, low-income Indonesian neighbourhood that was filthy and gloomy.
But residents of the Wonosari community in Semarang decided an extreme makeover was needed, and received money from the local government and several companies to carry out the project.
The houses were re-painted in a dizzying array of colours during a month-long overhaul which cost about USD 200,000, and the polluted river nearby was also cleaned up.
The buildings -- many of which are decorated with art such as pictures of angels' wings and whales -- can be seen for miles around, climbing up the hillside like a gigantic staircase.

Domestic and foreign visitors have been flocking to the village to snap pictures, which have been rapidly spreading on Instagram and Facebook.
"This is very special, extremely creative," Maya Susanti, an Indonesian visitor who came to the village with her friends told AFP.
Community leader Yosep Tri Prawoko added: "Every single alleyway has become a favourite spot for a photoshoot, it's great."
Villagers are enjoying the tourism boom sparked by the makeover.
Surani, a local flower seller who like many Indonesians goes by one name, said local people were feeling the benefits: "I hope our livelihoods keep on getting better."
The makeover and flow of visitors has also encouraged residents to keep the community clean, and rubbish bins have been put up around the hamlet.
