Prague miniatures museum

At the Museum of Miniatures (Strahovske navdori 11, Prague 1, Czechia; phone +420 233 352 371, www.muzeum miniatur.cz/en), the exhibits all must be viewed with microscopes. 

Using self-made tools, artists have created miniature sculptures so small, each can fit in the eye of a needle or even on the leg of a mosquito. Highlights — a flea with golden horseshoes, a portrait of author Anton Chekhov on a poppy seed and the Lord’s Prayer written on a human hair. Open daily, 9 a.m.-5 p.m. Entry, CZK150 (near $6.40).
