Walls and Alcazar of Segovia
The first defences for the walled town of Segovia were probably built in the Roman era. The current walls and Alcazar (fortress) are medieval. The Alcazar has since been used as a palace and a prison, but is now open to tourists. The walls fell into decline but more recently attempts have been made to preserve them and you can still walk along some parts of the walls. Together with the historic old town of Segovia, the wa ...Kraków Defence Walls
The defences of Kraków date back to the 13th century and consisted of a wall with 39 towers and 8 gates, surrounded by a moat. The Wawel Castle defended one end of the town, and the Barbican the other. Today you can still see the Castle and the Barbican, and a small section of the wall by St Florian"s Gate. But the site of the old wall has been replaced by a garden, The Planty, that encircles the city. As you walk ...Medieval Walls of Avila

Goseck Circle
The Goseck circle is a Neolithic circle structure. It may be the oldest and best known of the Circular Enclosures associated with the Central European Neolithic. It also may be one of the oldest Solar observatories in the world. It consists of a set of concentric ditches 75 metres across and two palisade rings containing gates in places aligned with sunrise and sunset on the solstice days.
Its construction is dated to c. 4900 BC, and it seems to have remained in use until 4600 BC. This corresponds to the transitional phase between the Neolithic Linear Pottery and Stroke-ornamented ware cultures. It is one of a larger group of so-called Circular Enclosures in the Elbe and Danube region, most of which show similar alignments.
Excavators also found the remains of what may have been ritual fires, animal and human bones, and a headless skeleton near the southeastern gate, that could be interpreted as traces of human sacrifice or specific burial ritual. There is no sign of fire or of other destruction, so why the site was abandoned is unknown. Later villagers built a defensive moat following the ditches of the old enclosure.
The Goseck ring is one of the best preserved and extensively investigated of the many similar structures built at around the same time. Traces of the original configuration reveal that the Goseck ring consisted of four concentric circles, a mound, a ditch, and two wooden palisades. The palisades had three sets of gates facing southeast, southwest, and north. At the winter solstice, observers at the center would have seen the sun rise and set through the southeast and southwest gates.
Archaeologists generally agree that Goseck circle was used for observation of the course of the Sun in the course of the solar year. Together with calendar calculations, it allowed coordinating an easily judged lunar calendar with the more demanding measurements of a solar calendar.
