Castles? Well acutally this kind of structure dates back to the Dark Ages in Europe, if by that you mean a moat, drawbridge. portculis. turreted walls, and a central keep and dungeon.  I don't know if maybe even if the Romans and other societies in Europe had them too, but there are indications that some kind of fortifications were in use in Indo European times as far back as 10,000 BC.\n\nI think any static, non nomadic culture any where might have created a place to gather and defend them selves against raids and predations from other tribes. -

Volcanoes are not more active then they were 100 years ago, it just seems that way because there are more humans and better communication now, so more eruptions are witnessed and reported.\n\nIf any thing there are actually less eruptions and lower intensity eruptions today, then there were a few thousand years ago.

You think we are seeing lots of volcanic activity NOW?\n\nRent a copy of Walt Disney's "Fantasia" and watch the part about the early ages of the Earth.\n\nFor millions of years, all this planet DID was erupt.\n\nOf course, your question is tied more to relatively recent times.  The planet seems to pass through periods of greater and lesser volcanic activity.  Much of it is stimulated by movement of the great "tectonic plates" on which our globe is formed.  These are huge chunks of the Earth's crust that slide and bump into one another.  They "float" on top of the more liquid, or molten, components of the Earth's core.\n\nVulcanologists, or specialists in volcanoes, can answer your question with greater precision.  In general, there has been an apparent increase in volcanic activity over the past 40-50 years.  That's how long I've been paying attention, anyhow.  But some of this appearance of activity is a product of remembering volcanic events - a few this year, another one or two some years later, and so on.  Most what I have noticed is that volcanic activity seems to have moved around the world.  Where one volcano goes ka-boom, or squirts out some lava for a time and then goes quiet, later there's a new one doing the same elsewhere.  After a time, it seems there are lava flows everywhere, when in fact there are not.\n\nThe most persistent volcanic activity I can remember is in Hawaii, where for at least 20 years (or so it seems) the Big Island has slowly been growing as a result of constant lava flow.\n\nThe 1800's overall seem to have been far more active in terms of volcanic eruptions and disasters than the past 100 years.  Some of the most horrendous volcanic disasters took place in that century.\n\nWe should remember that ours is not a "quiet" planet, but an ever-active ball of dirt, water and air.  It's an interesting place, eh?

It is supposed to be more than 2000 years.\nSee reference article.

he few roads that still existed were in a bad state, bridges were scarce, and brigands were common. For this reason during the Dark Ages, which lasted until about 1000 A.D., populations were tightly bound to the land surrounding the feudal lord's castle. People moved about only when there were festivals in other cities. These were the only occasions on which people could buy or look at different goods and have a chance to sell their own food or objects and fabrics made for sale. Fear controlled people’s lives and induced them to ask for protection from powerful warriors who had constructed well-defended castles, or from monasteries, which did not have soldiers but did have thick walls to hide behind. Life was hard, and , people thought little of clothing. Clothes were often made at home and were often rough and shapeless. Trousers, tunics and shawls were used to keep away the cold. The shawls were made of wool or fur and put over the shoulder. Most Europeans were dressed like today’s Benedictine monks, except for men’s trousers. Shoes were leather wrapped around the foot. Colors were plain; they were shades of gray, brown, dark blue and red. Conical hats were commonly worn.\n\nThis was a pyramidal society because the classes of people were in a shape of a pyramid.. with the kings and queens at the top of the pyramid (and were few in number) down to the peasants (who were many in number). In the middle were feudal lords, clerics, and others, such as vassals.\n\nTAILORING\nIn the Middle Ages, for the wealthy, most clothes were created by tailors. Some fabrics tailors used were : Burnet, perse, lincoln scarlet, kersey, russet, chalons, damask, and sandal. (Most of the population, however, made their clothing themselves).\n\nCLOTHING\nOften, kings and queens would wear crowns and brightly colored silks. Obviously, their clothing was very expensive and only they had enough money to afford such beautiful things.\n\nShoemakers and their spouses often wore borealis hats. The clothes they wore with that were woolen coats with fur-trimmed sleeves. Inside the coat was a woolen doublet.\n\nHoly orders, such as friars, wore cloaks with hoods and habits. On their clothes was a rope belt with wooden beads for counting prayers.\n\nFelt hats with stirrups and brown jackets were the daily wear of manor lords. Peasants' daily wear was simple: straw hats that they made themselves, linen shirts that they made themselves, leather flasks, hoses (pants), and pewter badges or good luck charms.

Depends on what criteria you set, but the Deccan Traps in India 60- to 65Ma ago was very large. It was classed as a supervolcano much like the one in Yellowstone park at the moment. \nAlthough some people claim that the formation of Yellowstones caldera around 2 million years ago was the largest volcanic eruption ever.

If you are talking about the legendary castle:  It depends on who is telling the story.  Different versions of the legend, from the ancient folk tales to the Victorian poets.  The first link has different retellings of the Arthurian legend.\n\nIf you are talking about the historical figure of Arthur, who may or may not have existed:  There is a sight in Cadbury, England, which is usually pointed to as the "historical Camelot;" it was an ancient hillfort.  There have been stone age, Roman and Saxon artifacts unearthed in the area.  Life inside and around its walls depended on who was in charge at the time, and whether there was peace or war.  It was probably a site of battles, as well as a place of residence.  The second two links have information about the Cadbury site.

The oldest megaliths in the world are located on the islands of Malta and Gozo. Archeologists have dated the stone structures of Ggantija (the Giant's Tower), Hagar Qim, Tarxien, and Mnajdra to about 5200 BCE. The first settlers arrived on Malta and Gozo around 5000 BCE from Sicily.\n\nRead more about it here:\nhttp://www.hmml.org/centers/malta/history.html

The volcanic period in Wales extended from the Late Jurassic into the Early Cretaceous, peaking in the Aptian stage, about 113-119 million years ago. The mountains of north Wales are the remains of a huge volcanic plateau. The terrain has been greatly modified since that time by glacial movement during numerous ice ages. Today, it would be almost impossible to locate specific ancient volcanoes in the region.

Stone, mortar, wood-these were the simple components used to construct some of the most heavily fortified structures ever created.\n\nEarly castles relied on the surrounding landscape to provide much of the protection. Early castles were made of wood and built on hills of "mottes". Surrounded by a high, wooden palisade, motte and bailey castles were used widely until the Norman invasion of 1066. These fortifications proved too easy to burn, and stone was then used more frequently.\n\nCastles were rarely the most comfortable place to live, with only the lord and his family given adequate heat and other amenities. Medieval castles were built for safety, not comfort. Windows were little more than slits in the wall. Cold, stone floors and walls rarely kept in heat, and water had to be brought by the bucketful throughout the castle. Walls were built high to protect from advancing armies, and to provide needed lookout positions.\n\nFor detailed information, visit: http://www.medieval-castles.net/castle_architecture/index.htm\n\nThe simple stone and mortar architecture made repairs fairly easy to make. It was not uncommon for stones to be used over and over with each successive castle built on the same location. Cannons and gunpowder made the castle ineffective and these large structures evolved in the later Middle Ages and Renaissance to become manor homes and palaces.

Check these sites out.\n\nIt was the first château at Chaumont-sur-Loire, Loir-et-Cher, France. \n\nThe sites are full of interesting facts (especially the third one).  Good luck.  =)
