The Gevangenpoort (Prisoner's Gate) is a former gate and medieval prison on the Buitenhof. From 1420 until 1828, the prison was used for housing people who had committed serious crimes while they awaited sentencing.
Its most famous prisoner was Cornelis de Witt, who was held on the charge of plotting the murder of the stadtholder. He was lynched together with his brother Johan on 20 August 1672 on the square in front of the building.
In 1882, the Gevangenpoort became a prison museum. The 'gate' function was lost in 1923 when the houses adjoining the Hofvijver were taken down to build the street that now allows busy traffic to run by it.
Since 2010, museum visitors can view the restored art gallery that can be reached through a special staircase that connects the two buildings. The collection which hangs here is a modern reconstruction of the original 1774 art cabinet that was situated upstairs above the fencing school. The paintings are again upstairs, hanging crowded together on the walls in the style of the late 18th-century. In 1822 the collection was moved to the Mauritshuis which remains the formal owner of the paintings on display. During restoration activities, highlights of the permanent Mauritshuis collection have been temporarily displayed in the gallery.
References: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.
