city gate

A city gate is the main entrance or exit point to a city, often part of a larger defensive wall or fortification. Historically, city gates controlled access for people, goods, and vehicles, helping to protect against invaders, regulate trade, and collect tolls. Today, many city gates are symbolic or architectural features preserving historical significance, while some still serve functional roles in traffic management or security. Overall, a city gate is a designated access point that defines the boundary between the city and its surrounding areas.
