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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
