Bokenäs Old Church is one of the most well-preserved medieval churches in Bohuslän. It was founded at some point in the early 12th century, and has been in use since. Except for parts of the interior, the weapon house from the 17th century, and the tower from 1752, most of the church is original. The church is open to the public daily during the summer, and for pre-arranged visits during the rest of the year, due to maintenance costs.

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.
