Big Merino, Concrete sculpture in Goulburn, Australia.

The Big Merino is a 15.2-metre-tall concrete merino ram in Goulburn, New South Wales, modelled on a stud ram named Rambo from the local property Bullamallita. Its steel frame is covered with wire mesh and sprayed with glassfibre-reinforced concrete, giving a rough, textured surface. The head has a broad muzzle and two horns curving outward, with heavy concrete folds hanging beneath the chin and down the chest. Thick blocky legs support the body on a large base.

The Big Merino was unveiled on 20 September 1985 by federal tourism minister John Brown, after an idea by brothers Attila and Louis Mokany. Adelaide builder Glenn Senner took six months to construct it over a steel frame with wire mesh and glassfibre-reinforced concrete, to architect Gary Dutallis's design. When the Hume Highway bypassed Goulburn in 1992, the site lost about 40 busloads of tourists daily; on 26 May 2007 the statue was moved nearer the new highway.

The ram is modelled on Rambo, a stud merino that lived on the local property "Bullamallita". Locals call the statue Rambo, and its eyes serve as an observatory over Goulburn. Inside, an exhibition traces the history of wool in Australia.

The site is easy to reach and can be viewed from the outside, but the interior includes stairs and viewing areas you can explore. It works best to visit during quieter hours, away from busy traffic times.

Visitors can climb up inside the sheep's head and look out through its eyes to see the landscape and town below. This unusual viewing spot gives you a feeling of what it's like to be inside a massive structure.
