A central business district (CBD) is the commercial and business center of a city. It typically features a high concentration of offices, retail shops, and cultural institutions. The CBD is often characterized by tall buildings and a bustling atmosphere, making it a hub for economic activity and employment. In many cities, the CBD is well-connected by public transportation, allowing easy access for workers and visitors. It serves as a focal point for business transactions and services, often housing major corporations, government offices, and financial institutions like banks and stock exchanges.
