The Tatarna Bridge (Γέφυρα Τατάρνας, Gefyra/Gefira Tatarnas) is a modern bridge over the Kremasta artificial lake. The bridge connects the Valtos province of Acarnania with the Evrytania prefecture. In the same place there was a 17th century historical and famous old arch stone bridge (over the river Acheloos). The name Tatarna comes from a nearby monastery.
Next to the old bridge was the largest spring of the Achelous, known to the locals with the name Mardacha (Μαρδάχα) which means "huge spring". The modern bridge (which was designed by the civil engineer Aristarchos Oikonomou) was constructed over the place where the old one was sunk. The architectural design for the bridge received three international awards referring to its unique method of construction. The GR-38 (Agrinio - Karpenisi - Lamia) runs over the bridge.
The first battle of the Greeks from Roumeli against the Turks during the struggle for independence, (1821), took place near the old historical bridge of Tatarna.
Not very far from the new bridge there is an abyss hole in the ground. According to confirmed information, by locals and others, many opponents of the E.L.A.S.(E.A.M.) organisation, (during the civil war) were thrown, dead or alive, inside the abyss hole. In this place a monument has been erected as a reminder of these events.
