A city made of a circular building 23 miles in circumference and 200 feet wide would be an innovative and unique urban development concept. The massive circular structure, standing about 100 feet tall, would offer a compact and efficient solution for living, working, and recreation.

The interior of the building would be divided into multiple levels, with each level serving a different purpose. The lower levels could be dedicated to transportation, with electric vehicle roads running along the circumference and connecting to tunnels for efficient travel throughout the city. There would also be parks and green spaces throughout the interior, offering residents a place to relax and enjoy the outdoors.

In addition to parks, the city would also have libraries, schools, and residences. The libraries would be state-of-the-art facilities, offering residents access to books, internet, and educational resources. The schools would provide quality education for the city’s youth, and the residences would offer comfortable and affordable living spaces for the city’s residents.

The circular shape of the building would provide a compact and efficient solution for urban development, with all the necessary amenities and services located within close proximity. The electric vehicle roads and tunnels would reduce traffic congestion and pollution, making the city more sustainable and environmentally friendly.

Overall, this circular city would offer a unique and innovative solution for urban development, providing residents with a compact, efficient, and sustainable environment to live, work, and play.
