Wallarobba Arts and Cultural Centre was established in 2011 and has become the centre of Hornsby's art world. It's a place to visit whether you're an artist yourself or just curious about the latest exhibition.
For almost as long as it's been around, the centre has been home to the Hornsby Art Society, a community of artists who have a a range of backgrounds and interests. The society began 1964 but has since become formalised and developed close ties with Hornsby Shire Council.
Lots of art schools run classes and tutorials at the centre too. These include classes for children, beginners and artists wanting to learn special techniques (like using watercolours). Local art groups meet here and talks are held by the society in the hall behind the centre. Links to all of these activities can be found here.
On Fridays, between 9.30am to 4.30pm a purpose-built printmaking studio also opens for artists to use for free. Sessions are run by local artist John Crawford and bookings are required.
Though the centre has only recently been established, the old homestead that contains it is quite old (it was built in 1903). It's full of maze-like rooms that are small but decorative, with a (creaky) wooden staircase to the second floor. Definitely not made for exhibitions (I ended up walking into an office space wondering if the room was part of the exhibit), but more interesting than uniform white walls.
To find the centre, you need to use the driveway behind Willow Park. Both attractions share the car park here, which is free but not extensive. The place is also conveniently situated within walking distance of both Waitara and Hornsby Stations, and there is a bus stop right outside.
A similar attraction not too far away, which offers the chance to see exhibitions within a converted old building, is the Grace Cossington Smith Gallery, over on the grounds on Abbotsleigh School for Girls in Wahroonga. It uses the bottom floor of a century-old boarding house for a program of month-long exhibitions.
