To the southeast of Dulwich Park, on the busy South Circular road, is the wacky Horniman Museum , purpose-built in 1901 by Frederick Horniman, a tea trader with a passion for collecting. The museum is principally a monument to its creator's freewheeling eclecticism: in addition to its small aquarium and its large collection of stuffed creatures, there's a wide-ranging anthropology section, and a musical department with more than 1500 instruments from Chinese gongs to electric guitars. However, the latter, and the new "centre for understanding the environment", are both undergoing massive rebuilding programmes, and won't be open to the public until 2002.
