Мавзолей-костница на връх Средногорец

It is a historical place located on the main road Smolyan – Rudozem, just few kilometers after the village of Polkovnik Serafimovo. There is a Monument and a Mausoleum erected there in the memory of the soldiers from 21^st Infantry Regiment killed in the epic battles that led to the Liberation of the Middle Rhodopes from the Ottoman rule. In 1934, in honor of these memorable events and of the leader of the Infantry Regiment – Collonel Vladimir Serafimov, the village of Alamidere was named after him.
