One of the biggest art projects Bloemfontein has ever seen. That is how Angela de Jesus, curator of the Johannes Stegmann Art Gallery at the University of the Free State (UFS), describes It’s My City. And the large-scale public art project involves the community of Bloemfontein/Mangaung’s participation.

The artwork, conceived by British artist, Alex Rinsler, will be on display from 8 to 16 July 2016, alongside the Vrystaat Arts Festival. Three sculptures, a Baby Giraffe, Mother Tree and Toy Windmill, each about 7.5 metres, will appear in Hoffman Square, Mapikela Square in Batho location, and on the Red Square of the UFS Bloemfontein Campus respectively.

Many from around the city included


Local lead artists – Marius Jansen van Vuuren (Baby Giraffe), Tshiamo Art and Crafts Development (Mother Tree), and Minè Kleynhans (Toy Windmill) – expressed their relationship to the city. According to De Jesus, the project includes “six artists; more than 20 job opportunities were created; and there were skills transfer for many more. Over 50 volunteers, 100 professionals, and hopefully thousands will take part.” It’s My City is the signature 2016 project of the Programme for Innovation in Artform Development, a partnership between the UFS and the festival, supported by the Andrew W. Mellon Foundation and the municipality of Mangaung.

People can connect in positive way

“What most excites me is that this work will create imagery that loads of people can connect with in a positive way, and write a new story,” says Rinsler. According to the public artist and cultural producer, people are invited to visit the sculptures, write down their wishes for the city and those they love, and add them to complete the artworks.

Sculptures meet each other at ceremony

On 16 July 2016, the sculptures will be led by three processions, convening at the Macufe village (corner of Elizabeth and Markgraaff streets). At 17:30, a short ceremony, free to attend, will follow where they will be dismantled in spectacular fashion, with graceful fire and pyrotechnics, and so bringing together many people’s wishes as one.
