Elhovo
Elhovo lies on the Tundzha in southeastern Thrace, between the Sakar and Strandzha uplands. Its Ottoman name, Kızılağaç, refers to the alder tree, as does the Bulgarian name. The settlement came under Ottoman rule in the fourteenth century and developed as a centre for the surrounding district. Tax registers record it under several forms of its Ottoman name; sixteenth-century documents also mention its judge in connection with orders concerning the region's flocks and their movement towards the capital.
