The Classicist main building of the Õisu Manor was built at the turn of the 18th and 19th centuries. The wide and high parade staircase with sculptures of white marble makes the mansion impressive; one of the sculptures is a Protege of Home, the other one symbolizes Power. Many outbuildings belong to the Manor Ensemble, of which one of the most interesting one is the so-called "wry stable". There is an English-style park, one of the first in Estonia, behind the main building.

Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
