The Park Lands are divided up into 30 named and numbered Parks and 6 named squares.
The Park numbers are based on the old 'land section' numbers.
Karrawirra (Park 12) usually refers to the area north of Victoria Drive but historically, much of the University precinct between North Terrace and Victoria Drive was once Park Lands as well.
Land to the south-west of this corner, back to North Terrace gradually disappeared as Park Lands after the Adelaide University was founded in 1875.
What you will see on this walk is the part of Karrawirra that is still (mostly) intact as Park Lands.
It's very precious as part of a dwindling Park Lands buffer between the city and North Adelaide.
What remains today of Park 12 is 14 hectares in size. That seems like a large area of land, and it is – it could be cut up into about 200 standard size house blocks. But in the context of the whole Adelaide Park Lands, Karrawirra is only small, comprising just two percent of more than 700 hectares.
