The existence of VIRA town literally started with the construction of the Monastery Temple of Panayia Kosmosotira in 1152 by Isaakios Komninos, son of Alexios Komninos, emperor of Byzantine- who founded the Monastery of Panagia Kosmosotira near the Evros river and by the road connecting Traianoupolis and Constantinople. The monastery was protected by a great fortified wall and soon became the core of a city, developed by the gathering of habitants from neighbouring settlements.
