The city centre has retained architecture from the late 19th and early 20th centuries, particularly the interwar period, which is often seen as the 'golden age' of Bucharest architecture. During this time, the city grew in size and wealth, therefore seeking to emulate other large European capitals such as Paris. Much of the architecture of the time belongs to a Modern (rationalist) Architecture current, led by Horia Creangă and Marcel Iancu.
