In the summer of 1868, preparations for the construction of the castle began. It is particularly interesting that in September 1869, King Ludwig II had the building plan, various portraits of himself and coins from his reign placed in the cornerstone. The foundations of the castle are made of cement, the castle walls are made of bricks and the magnificent building was clad with light limestone. Neuschwanstein was opened to the public in 1886 only after the death of King Ludwig II, as the king was very shy and at the end the castle was his personal retreat.
