Hakoinen Castle was an ancient hill fortification, but nowadays there's only some ruins left. Dated medieval, the fortification was situated on a very steep rock by lake Kernaala (Kernaalanjärvi) reminiscent of a hill fort tradition. The top of the rock is 63 meters above the water level in the lake. Today very little remains of the castle. Equally little is known about its origins. One postulation is that it was built by the Swedes as their original stronghold in the medieval Häme area.
The castle was probably built at the end of the 13th century or during the early 14th century. It has been speculated that Hakoinen might have been the fort that was attacked by invading Novgorodian forces in 1311 during the Swedish-Novgorodian Wars, as described in the Novgorod Chronicle.
Eventually Hakoinen was left out of use. Some activity seems to have remained there until 1380s. The castle rock was later a part of a large estate belonging to the bailiff of Häme Castle. According to excavations, the castle was divided into two parts. Lower defensive constructions were mostly made of wood. Constructions on the rock were made of bricks and rocks. The castle probably had one tower.
Although very little remains of the castle, the medieval flora and huge sights from the top of the hill makes Hakoinen castle hill interesting place to visit.
Arlington National Cemetery is one of the most famous cemeteries in the world. The United States military cemetery was established during the Civil War on the grounds of Arlington House, which had been the estate of the family of Confederate general Robert E. Lee"s wife Mary Anna Lee. On June 15, 1864, the Arlington House property and 200 acres of surrounding land were designated as a military cemetery as Quartermaster General Montgomery C. Meigs wanted to ensure that Lee could not return to the site.
Today the cemetery is the final resting place for more than 300,000 veterans died in every American conflict, from the Revolutionary War to Iraq and Afghanistan.
The first soldier to be buried in Arlington was Private William Henry Christman of Pennsylvania on May 13, 1864. The most famous people buried to Arlington are Presidents William Howard Taft and John F. Kennedy. Also Kennedy"s two brothers, Senator Robert F. Kennedy and Senator Edward 'Ted' Kennedy, and General of the Armies John J. Pershing are buried there.
