The oldest mural paintings in the Netherlands are hidden in a beautiful church on the outskirts of Sittard-Geleen. It might be somewhat confusing that there are two churches with the same name in the same village, but you can probably skip the new church in the centre that was built in 1922. The church replaced the ancient one at the castle, which you definitely shouldn't miss if you're in the region.
The history of the old Salviuskerk can be traced back to the late 10th century, but all that remains of the original church hall is the northern wall made of boulders from the River Meuse. Over the centuries, the church was enlarged several times and the tower was erected in 1458. During a restoration in 1977, murals from around 1300 were found. The paintings have been restored and after almost two years of tremendous efforts, which included the stripping of at least 20 layers of lime paint, are now on display. The paintings depict a Mary-themed cycle with portrayals of the childhood of Christ, the coronation of Mary and the salvation. Another sacred item found in this church is a box that supposedly contains pieces of Saint Salvius' bones.
The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
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.
