Venice is a marvel for students of urban planning - the buildings form a series of interconnecting alleys and courtyards, forming a stimulating maze of voids and volumes.
One must diligently explore the city in order to fully appreciate its wonders. Hidden away, unmarked, are numerous treasures of medieval and renaissance architecture and murals.
A trip on the city's many water buses is a good way to cool off in the summer heat, while taking an inexpensive tour of Venice - seen from a perspective unavailable to the land-lubber.
