Lima is home to some wonderful museums including:
The Archaeological Museum
Located in a grand colonial house, the National Archaeological Museum gives a great insight into the many pre-Inca cultures of Peru, as well as the more well known Incas, with many fascinating exhibits. Exhibits include: textiles, ancient metals and two important ancient carved stone monuments.
The Larco Herrera Museum
An amazing private collection, this museum offers an excellent overview of 3000 years of pre- Columbian Peruvian history. Ironically the beautiful colonial house and pleasant walled gardens, hosting the collection are built on the site of an historic 7th century pre-Columbian pyramid. Exhibits include: ancient gold, silver and ceramics.
