The individual components that make up Dreienfels were designed by Siegmund in the 1950s and 1960s.
Originally, it consisted of three separate castles called Stolzeneck, Hoheneck, and Siegmundseck, each printed on a single sheet.
The publisher later decided to combine the three small castles into a single set (item S-71226) to allow for the construction of a larger fortified complex.
