I ordered this book from the mid-80's recently which I had always wanted to read. It's a wonderful book for fantasy aficionados and castle lovers everywhere. The book is broken down into three chapters with beautiful watercolor and pencil illustrations by Alan Dee, and text by David Day. The first chapter details castles from myths such as the Valkyrie's Tower, the citadel of Asgard, the Ice Castle of Utgard-Loke, and the Castle of Balor, to name a few. The second chapter deals with castles from the Age of Romance - from Camelot to the court of Charlemagne to Siegfried and the Rhine Castles.
The last chapter reflects upon castles from fantasy literature - the Castle of Earthly Paradise, Oberon's Castle of Gold, Dracula's Castle, Poe's Castle of the Red Death, Barad-Dur, the Dark Tower of Mordor and Minas Tirith from Lord of the Rings, and even Gormenghast from Mervyn Peake's the Gormenghast Trilogy.
The writing complements the illustrations nicely, reminding me of the story flow from the Time Life Enchanted World book series. There are many myths I was familiar with (Norse mythology, King Arthur, Beowulf, the Tuatha De Danaan), but I was pleasantly surprised at the tales I didn't know - the Polish tale of a castle that sat upon a mountain of pure glass, Jack the Giant-Killer and the Castle of Galigantus, Amadis and the Castle of Apollidon on the Firm Island, Dietrich and the Castle of the Ice Queen, and the Bloody Castle of Altaripa.
