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 Temple of Edfu is one of the best preserved ancient shrines in Egypt. It was built in the Ptolemaic Kingdom between 237 and 57 BC.
Edfu was one of several temples built during the Ptolemaic Kingdom, including the Dendera Temple complex, Esna, the Temple of Kom Ombo, and Philae. Its size reflects the relative prosperity of the time. The present temple initially consisted of a pillared hall, two transverse halls, and a barque sanctuary surrounded by chapels. The building was started during the reign of Ptolemy III Euergetes and completed in 57 BC under Ptolemy XII Auletes. It was built on the site of an earlier, smaller temple also dedicated to Horus, although the previous structure was oriented east–west rather than north–south as in the present site.
