Soldiers, merchants and travellers moved along it, and the settlement around the station supported that traffic. The valley gave a natural passage through difficult terrain, while the river served as a geographic guide. The name itself, from Old Greek for <em>belt, bandage, barrier<\/em>, hints at the site&#8217;s role in controlling the pass.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-2 is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" data-id=\"2183\" src=\"https:\/\/bronicable.com\/en\/wp-content\/uploads\/2026\/07\/places-sostra-01.jpg\" alt=\"Information board about the Roman road through the Troyan Pass near Fortress Sostra\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" data-id=\"2184\" src=\"https:\/\/bronicable.com\/en\/wp-content\/uploads\/2026\/07\/places-sostra-02.jpg\" alt=\"Stone Roman arch at Fortress Sostra near Troyan, Bulgaria\" \/><\/figure>\n<\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">The camp, the walls and the gate<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Construction began around <strong>147 AD<\/strong>, under Emperor Antoninus Pius, when the Second Cohort of Mattiaci was garrisoned here.
