A portico is a structure consisting of a roof supported by columns, typically found at the entrance of a building. It serves both functional and aesthetic purposes, providing shelter from the elements while enhancing the architectural appeal of the structure. Porticos are commonly seen in classical architecture, often associated with styles like Greek and Roman. In addition to residential buildings, porticos can be found in public spaces, such as temples, museums, and government buildings. They create a welcoming atmosphere and can serve as transitional spaces between the outdoors and indoors, inviting visitors to enter while offering protection from rain or sun.
