Sucre is Bolivia's fifth largest and most beautiful city. Founded by the Spanish in the 16th century, Sucre has a peaceful, European feel. The city has been designated as a UNESCO world heritage site to protect its many pristine and historically significant buildings. Largely untouched by tourism, the youthful city is a goldmine of unexplored treasures and cultural activity. It's also one of the cheapest and safest cities in South America, making it the perfect place to visit or live.
