Asenid The monument commemorates the 800th anniversary of the foundation of the Second Bulgarian Kingdom and its czars. In it Asen, Petur, Kaloyan and Ivan Asen II are represented atop their horses with a great sword which at a glance looks like a large black obelisk. These four czars ruled between 1185 and 1241.
