Not far from Cardiff Central Station.
A public plaza- with space for 120 bikes and a statue of the late great Betty Campbell MBE.
The Abacus occupied the space whilst the Council waited for commercial tenants- eventually Boots, Greggs and Tesco- to move in.
Though it was only open for a short time, the Abacus housed many community projects.
The Abacus launched in June 2014 as an arts space for everyone: students, commuters, locals, Cardiff, the Valleys, the world.
The Abacus closed in December 2015. Its memory lives on through its Facebook page.
The Abacus hosted a huge variety of events. It was also an example of collaboration between non-profit ProMo-Cymru and local artists' collective, The Modern Alchemists.
Bands at the closing party included Junior Bill, the same ones who did that "There's a Wolf in Grangetown" stunt recently.
It's awesome that Betty Campbell MBE is being honoured in the new development. She was Wales' first black headteacher, and a legend besides.
