Cassic Castle

Castle (1978–1983)
Castle is the first LEGO Castle theme, and, like Space, is still very popular. 375 Castle(often called the Yellow Castle) is the most well known set from this theme. Often known by fans as "Original Castle", the knights featured unique movable visor pieces, with eye slits, and a crest that runs backwards from the frontward-facing part of the visor along the helmet. These knights also wore a coat of arms (either a tunic or breastplate) over their body. It was not again until 1990 when knights came with movable visors and armor breastplates, as the knights between 1984-89 had solid grill helmets while their "armor" was just a texture on their body. As there were no horse specific pieces, horses were built entirely of bricks.
