Although the phenomenon known as the "White
Nights" is not unique to St
Petersburg, in no other northern city have they
received such poetic and literary acclaim. What could be more romantic than a
walk along the banks of the city's rivers and canals in almost broad daylight,
no matter what the time of day? No other major European city can rival this
experience nor the atmosphere on the streets of St. Petersburg during the summer months -
lively, friendly, romantic and bustling with people throughout the night as
well as the day!
From late May to early July the nights are bright in St Petersburg, with the
brightest period, the White Nights, normally lasting from June 11th to July
2nd. The White Nights (Beliye Nochi) are a curious phenomenon caused by St.
Petersburg's very northerly geographical location - at 59 degrees 57' North
(roughly on the same latitude as Oslo, Norway, the southern tip of Greenland
and Seward, Alaska). St. Petersburg
is the world's most northern city with a population over 1 million, and its
stands at such a high latitude that the sun does not descend below the horizon
enough for the sky to grow dark. In fact night becomes curiously
indistinguishable from day, so much so that the authorities never need to turn
the city's streetlights on!
