Sucre .

In 1991 UNESCO declared the city a 'Patrimonio Histórico y Cultural de la Humanidad' (World Cultural Heritage Site) and it's easy to see why. It's an absolute must for enthusiasts of colonial religious architecture, with many beautiful churches, all painted white. In keeping with colonial tradition, the entire core of the city is painted white, earning it the name of 'La Ciudad Blanca'. Sucre is not just a colonial museum, though, but a thriving university city. It is known as the student capital of Bolivia and thousands of students fill every street, plaza, bar and café. There are two universities, the oldest, Universidad Mayor de San Francisco Xavier, dates from 1624. This was the main source of libertarian thought and gave birth to the very first demands for independence heard on the continent, on 25 May, 1809 . In addition to the local students, Sucre sees many foreign students taking Spanish lessons and working as volunteers.
