Context: Guthrie is a village in Angus, Scotland, roughly at the centre point of the towns of Arbroath, Brechin and Forfar.  The principal building in the village is Guthrie Castle, which has its own public golf course and is a popular venue for events such as markets, parties and weddings.  The village of Guthrie is centered on the Guthrie parish church, containing the Guthrie Aisle, built in 1150. The naval history of Korea dates back thousands of years since the prehistoric times when simple fishing ships were used.  Military naval history dates back to the Three Kingdoms period and Unified Silla dynasties of Korea in the 7th century.  Because of the constant coastal attacks by the Wa Japanese and other barbarian tribes, Korean shipbuilding excelled to counter these threats as a result.  During the Unified Silla period, Jang Bogo, a merchant, rose as an admiral and created the first maritime trading within East Asian countries.  During the Goryeo dynasty, sturdy wooden ships were built and used to fight pirates.  Korean shipbuilding again excelled during the Imjin war, when Admiral Yi defeated the advancing Japanese fleets. Guthrie Castle is a castle and country house in Angus, Scotland.  It is located in the village of Guthrie, 10 km east of Forfar, and 29 km north-east of Dundee.  The castle dates back to the 15th century, although much of the present building is of 19th-century origin.  It is now a private house. The Chiesa Matrice is a church in Erice, Sicily, southern Italy.  It dates back the beginning of the 15th century (an original fresco dates back to 1420) and is built in the shape of a Latin cross with two entrances.  The church is enriched by numerous Baroque altars and paintings from the 17th century.  A silver statue of St Anthony of Padua dates back 17th century and is an example of Neapolitan silver-craft. Education in Sri Lanka has a long history that dates back two millennia.  The Constitution of Sri Lanka provides free education as a fundamental right.  Sri Lanka's population had an adult literacy rate of 96.3% in 2015, which is above average by world and regional standards.  Education plays a major part in the life and culture of the country and dates back to 543 BC.  Sri Lanka's modern educational system was brought about by its integration into the British Empire in the 19th century.  Education currently falls under the control of both the Central Government and the Provincial Councils, with some responsibilities lying with the Central Government and the Provincial Council having autonomy for others. The Handboogdoelen ("longbowmen's shooting range") is a building on the Singel canal in Amsterdam, near Koningsplein square.  It dates back to the early 16th century and originally served as headquarters and shooting range of the local "schutterij" (civic guard).  Most of the current building at Singel 421 dates to the 18th century and is part of the main complex of the Amsterdam University Library.  The Doelenzaal hall on the ground floor of the building (not to be confused with the Doelenzaal on Kloveniersburgwal canal) is used for lectures, meetings, receptions and doctoral dissertations.  The building has "rijksmonument" status. A house of cards (also known as a card tower) is a structure created by stacking playing cards on top of each other.  "House of cards" is also an expression that dates back to 1645 meaning a structure or argument built on a shaky foundation or one that will collapse if a necessary (but possibly overlooked or unappreciated) element is removed.  Structures built by layering in this way, such as Stonehenge, are referred to as "house of cards architecture", which dates back to the Cyclopean and Megalithic ages.  The origin of the phrase is debated to be from the 18th century England but some believe that it has an American base. The history of Lithuania dates back to settlements founded many thousands of years ago , but the first written record of the name for the country dates back to 1009 AD.  Lithuanians, one of the Baltic peoples, later conquered neighboring lands and established the Grand Duchy of Lithuania in the 13th century (and also a short-lived Kingdom of Lithuania).  The Grand Duchy was a successful and lasting warrior state.  It remained fiercely independent and was one of the last areas of Europe to adopt Christianity (beginning in the 14th century).  A formidable power, it became the largest state in Europe in the 15th century through the conquest of large groups of East Slavs who resided in Ruthenia.  In 1385, the Grand Duchy formed a dynastic union with Poland through the Union of Krewo.  Later, the Union of Lublin (1569) created the Polish–Lithuanian Commonwealth that lasted until 1795, when the last of the Partitions of Poland erased both Lithuania and Poland from the political map.  Afterward, the Lithuanians lived under the rule of the Russian Empire until the 20th century. Mount Pantokrator (sometimes Pantocrator, "Pantōkrator", Παντοκράτωρ in Greek) is a mountain located in north-eastern Corfu.  At 906 m , it is the highest mountain on the island.  At the summit, the whole of Corfu can be seen, as well as Albania which lies a short distance from the island.  On particularly clear days it is also possible to see Italy despite it being around 130 km away.  At the top there is a café for tourists, a telecommunications station, whose largest tower stands directly over a well, and a monastery.  The first monastery on the site was Angevin, built in 1347 but then destroyed sometime around 1537.  The current church on the site dates from around 1689, and the current facade was built during the 19th century.  It is dedicated to the transfiguration of Christ.  To get to the peak, you can either drive to Mount Pantokrator up a series of windy roads from the coast, or walk to the top.  If you choose to walk, one of the best places to start is in Old Perithia, Corfu's oldest village, where it takes approximately 2 hours round trip.  The village of Old Perithia dates back to the 14th century and the 'Perithians' helped build the original monastery using local wood and limestone.  The village of Old Perithia (and the now abandoned village of Sinies) can be seen from Pantokrator and with its 130 house and 8 churches Old Perithia is said to sit at the foot of Pantokrator, 'The Almighty.'  The walk to Pantokrator is also part of The Corfu Trail, an established walking guide around the island of Corfu, although they fail to maintain the paths, so walks such as Perithia to Mt. Pantokrator are now nearly impossible to detect. East Marden is a village on the spur of the South Downs in the Chichester district of West Sussex, England.
