Trikala, Smart city in Thessaly, Greece
Trikala is a city in central Thessaly, Greece, that spreads along the Lithaios River and is connected by several bridges. Pedestrian zones run through the town center and link residential areas with shopping streets, while parks along the riverbank serve as meeting points.
The ancient settlement of Trikke held a sanctuary of Asclepius that drew patients from across the Mediterranean and served as a major medical center. During Byzantine and Ottoman times, the city grew along the riverbank and developed separate quarters for different communities.
The Varousi district sits along the riverbank and shows steep cobblestone lanes with houses built into the hillside, while the adjacent neighborhoods offer flat squares with cafes and shops. Local festivals often take place in these squares, where residents gather in the evening for food and conversation.
The pedestrian zones in the center make walking easy, and most shops and restaurants are within a short distance from one another. Digital displays at bus stops show real-time information about arrival times and help with planning trips around the city.
A network of sensors measures air quality at different points across the city and shows the results on public screens, so residents stay informed about conditions. The system also adjusts street lighting intensity based on pedestrian traffic and dims lights on empty streets during the night.
