 ### Architecture
 
-Provide a high-level overview of the architecture of the TEF Site, including the key components and technologies used. Include any relevant diagrams or visualizations to help stakeholders understand the infrastructure.
+Milano TEF infrastructure enables seamless integration and real-time processing of IoT data across multiple urban deployment sites located in Italy.
+The sensors deployed in Cascina Merlata, Porta Romana, and the Mithraeum of Rome transmit data using heterogeneous communication protocols (MQTT, ZenoH, and LoRaWAN via The Things Network).
+Data incoming from our site locations is unified by corresponding FIWARE IoT Agents and delivered to a central FIWARE Context Broker, representing our infrastructure's central data exchange location.
+Our infrastructure supports reliable data storage (InfluxDB, MongoDB), continuous analytics, data aggregation using our custom streaming component (EsperTech), and access through Traefik and authentication layers.
+Finally, visualization and analysis tools (Grafana, Spark, Node-RED, Snap4City) enable real-time monitoring of our infrastructure and allow end users to extract environmental conditions insights, urban infrastructure usage, and system health.
