Defensive towers in Armenia

There are a number of free standing towers in Armenia, that were used at various points for self defense. All of these date from the Middle Ages to the 19th century. They were last used in defending against Lezgin or Persian invaders at the beginning of the 19th century, after that they fell to disuse.

1: Voskepar Tower (Tavush)
2: Sedvu Tower (Lori)
3: Sisi Fortress (Lori)
4: Meghri Fortress (Syunik)

Hopefully these can all be restored and re-roofed in the near future.
