Mingle with the most extravagant handlebar moustaches in Britain, pay your respects at the dog cemetery in Hyde Park, visit a Masonic temple, take trapeze lessons in a former power station, pray in a floating church, sail on a disused reservoir, discover the stone from which Arthur drew Excalibur, admire the sacred penis of a pharaoh, take aim on the City's last bowling green, go stargazing at Greenwich Observatory, examine a rare cucumber straightener, a stuffed mermaid or a cow's heart... Far from the crowds and the usual cliches, London still holds hidden treasures for those who know how to wander off the beaten track. An indispensable guide for those who thought they knew London well, or who would like to discover the hidden face of the city.
