Quarry Green is another small green space tucked away in the inner-city suburb of Ultimo.
Information about the area's history from the City of Sydney:
In the late 19th century, sandstone quarrying in Pyrmont and Ultimo declined as the quarries were worked out and brick replaced stone in building workingmen's houses. Other industries moved into the area, including flour mills, factories and wool stores. Wool was Australia's prime export.
In 1932 the Country Producers Selling Company built two large warehouses on the corner of Quarry Street and Bulwara Road. By World War II, 20 wool stores on the peninsula employed over 1,000 men, most of them in Ultimo.
Many of these wool stores were constructed with timber beams, and being soaked in wool grease, they became highly flammable. Spectacular fires were common in Ultimo, and many burned for days. In the early horus of the morning on 19 March 1978 a fire destroyed the old Country Producers warehouses. It was Sydney's biggest fire in 20 years, but nobody died.
After the fire, Quarry Street was partly closed, widened and landscaped to form Quarry Green. The park first opened in May 1983.
Be careful when retrieving the cache, as muggles are often nearby. There are two cafes across the road from GZ - there may be less people around after 3pm, when the cafes are closed for the day. Please also replace the cache securely to make sure it doesn't leave its spot.
