The castle of Lamia is located on the highest spot of the city on a rocky hill. From the top of the hill the castle “observes” the city and Sperchios river valley, Iti, Kallidromos, Parnassos, Gkiona mountain tops and Maliakos gulf.
It is one of the most important monuments in the area, not only for its medieval character but also for the Archeological Museum built in its interior. According to the findings in the castle walls there is a historic continuation from the 5th century B.C. up to the Second World War. The Ephorate of Prehistoric and Classical Antiquities, as well as Conventions center have their offices in the castle’s interior.
