There has been a wooden church in Källa since the 11th century. After it was destroyed by fire, and with increasing attacks from Baltic invaders, a new church of stone - with the aspect of a fortress - was constructed in stages was built in the 13th century. The two-storied construction, dedicated to St. Olav, was very unusual and made for defensive purposes.
The Källa Church fell into disrepair when a new church was built here in the nineteenth century, but has now been taken into the care of the National Heritage Board and is a major tourist attraction. The most valuable of the old Källa Kyrka's furnishings, including the 15th-century triptych carving and the pulpit from 1600, were moved to the new church.
In the churchyard many of the huge old flat gravestones date from the 1600's and 1700's. Older graves have been discovered from the 11th and 12th centuries.

The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. 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.
