Adelsnäs (formerly known as Näs) manor was named after Johan Adelswärd, who acquired the local copper mine in 1781. The present manor building was built Theodor Adelswärd in 1916-1920. English garden and parks around the Bysjön lake are popular when open to the public.
The unique detail is a “Sun Cannon”, which is installed in a red brick tower from 1853. It is a 6-pound cannon from the same period with an ignition system consisting of a magnifying glass mounted on a movable arm, adjustable to the sun’s different meridian latitudes. At exactly 1 pm, when the sun reaches its highest point at midday in summertime, the sun shines through this opening, hitting the magnifying glass focused on the priming compound at the back of the cannon.
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.
