However, many smaller arcades are demolished, replaced with large centers or malls, often accessible primarily by vehicle.
Technical innovations like electric lighting and escalators were introduced from the late 19th century. From the late 20th century, entertainment venues like movie theaters and restaurants began to be added. As one built structure, early shopping centers were often architecturally significant constructions, enabling wealthier patrons to shop for goods in spaces shielded from the weather.
