The well-designed Fundación Museo Amano (museoamano.org, adult/child S35/S15) features a fine private collection of ceramics, with a strong representation of wares from the Chimú and Nazca cultures. It also has a remarkable assortment of lace and other textiles produced by the coastal Chancay culture.
There's an optional 1.5-hour guided tour in English, Portuguese or Spanish.
