The Dalakova mound is located north-east of the village of Topolchane, near Sliven. In the summer of 2007, a TEMP expedition team led by Archaeologist G. Kitov, made an archaeological discovery. In the study of the mound necropolis, a rich Thracian royal tomb with grave gifts was discovered. Today, all these finds are located in the Regional History Museum in Sliven. Among the valuable artifacts found there were two gold phiales and a gold mask.
