Dumfries Museum and Camera Obscura is the largest museum in the region. The museum has extensive collections relating to local and history from the pre-historic era. The museum also has the world's oldest working Camera Obscura. Admission is free, however a small fee applies for the Camera Obscura.
The museum's collections cover all material relating to the natural history and human pre-history of the region, from geology to dress, folk material, archaeology and early photographs. Notable artefacts include for example a cast of the skull of Robert the Bruce, Bronze Age cist burial including the remains of a 35-year-old man from the beaker people and a large collection of Roman and Celtic stone crosses and funerary monuments.
Originally built as a four-storey windmill on Corbelly hill, the highest point in Maxwelltown, in 1798, the site was purchased by Dumfries and Maxwellton Astronomical Society in 1834. Over a two-year period the tower was converted into an Observatory, and with advice from polar explorer Sir John Ross, a telescope was purchased from a Mr Morton of Kilmarnock. With its completion in 1836, unfortunately the observatory missed the arrival of Halley's comet; however, it was used in this role until 1872.
The camera obscura is currently the oldest working example in the world, and has been in continuous operation since 1836. The instrument, based in the top level of the windmill tower, offers a complete 360° panorama of the surrounding landscape. The image is projected onto a focusing table below, and operated using a simple rope mechanism. In order to protect the instrument it is only operated during the summer months and on days when weather conditions are clear.
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.
