Petäjävesi old church was inscribed on the UNESCO World Heritage List in 1994. It was designed and built in 1763-64 by a local peasant master-builder, and in 1821 his grandson added the bell tower at the west end. Petäjävesi was then part of the Jämsä congregation, but the trip to Jämsä church was too long for local people. The Crown of Sweden had accepted the request to build a graveyard and a small village church at their own expense as early as in 1728, but building was delayed nearly forty years. The church was located to a typical old countryside site. It was chosen so that the parishioners got easily there by boat or in the winter stay over.
When the newer church was completed in 1879, old church was abandoded for nearly for decades. The period of neglect between 1879 and the 1920s was a blessing in disguise. The historical importance of the church was noticed first by the Austrian art historian Josef Strzygowski in the 1920s. After 1929 church is renovated several times.
Petäjävesi olf church is a very unique and well-preserved wooden church representing the wooden architecture tradition of eastern Scandinavia. Nowadays it’s a popular tourist attraction and open every day in summer time (in winter season by appointment).
The Church of the Savior on Spilled Blood is one of the main sights of St. Petersburg. The church was built on the site where Tsar Alexander II was assassinated and was dedicated in his memory. Construction began in 1883 under Alexander III, as a memorial to his father, Alexander II. Work progressed slowly and was finally completed during the reign of Nicholas II in 1907. Funding was provided by the Imperial family with the support of many private donors.
Architecturally, the Cathedral differs from St. Petersburg's other structures. The city's architecture is predominantly Baroque and Neoclassical, but the Savior on Blood harks back to medieval Russian architecture in the spirit of romantic nationalism. It intentionally resembles the 17th-century Yaroslavl churches and the celebrated St. Basil's Cathedral in Moscow.
The Church contains over 7500 square metres of mosaics — according to its restorers, more than any other church in the world. The interior was designed by some of the most celebrated Russian artists of the day — including Viktor Vasnetsov, Mikhail Nesterov and Mikhail Vrubel — but the church's chief architect, Alfred Alexandrovich Parland, was relatively little-known (born in St. Petersburg in 1842 in a Baltic-German Lutheran family). Perhaps not surprisingly, the Church's construction ran well over budget, having been estimated at 3.6 million roubles but ending up costing over 4.6 million. The walls and ceilings inside the Church are completely covered in intricately detailed mosaics — the main pictures being biblical scenes or figures — but with very fine patterned borders setting off each picture.
In the aftermath of the Russian Revolution, the church was ransacked and looted, badly damaging its interior. The Soviet government closed the church in the early 1930s. During the Second World War when many people were starving due to the Siege of Leningrad by Nazi German military forces, the church was used as a temporary morgue for those who died in combat and from starvation and illness. The church suffered significant damage. After the war, it was used as a warehouse for vegetables, leading to the sardonic name of Saviour on Potatoes.
In July 1970, management of the Church passed to Saint Isaac's Cathedral (then used as a highly profitable museum) and proceeds from the Cathedral were funneled back into restoring the Church. It was reopened in August 1997, after 27 years of restoration, but has not been reconsecrated and does not function as a full-time place of worship; it is a Museum of Mosaics. Even before the Revolution it never functioned as a public place of worship; having been dedicated exclusively to the memory of the assassinated tsar, the only services were panikhidas (memorial services). The Church is now one of the main tourist attractions in St. Petersburg.
