The Prague preservation area of Lesser Town is one of the most attractive highlights of Prague. The King Premysl Otakar II founded the so-called New Town below Prague Castle, called from the early 14th century the Lesser Town of Prague, in the outer castle settlement in the area of today's Lesser Town Square. The Emperor Charles IV substantially extended the settlement by including the neighbouring settlements and erecting new walls (the so-called Hungry Wall).
The today's shape of the Lesser Town comes mainly from the 17th and 18th century, the time of construction of pompous baroque palaces, churches and monasteries. In 1784 the Lesser Town lost its status of an independent town and became one of the districts of the united Prague.
