Leaning Tower of Pisa

The leaning Tower of Pisa is a medieval architecture, in Romanesque style. The construction of Tower of Pisa began in August 1173 and continued for about 200 years due to the onset of a series of wars. Till today, the name of the architect is a mystery.
The Tower of Pisa was designed as a circular bell tower that would stand 185 feet high. It is constructed of white marble. The tower has eight stories, including the chamber for the bells.

Sutyagin House

The Sutyagin House was a wooden house in Arkhangelsk, Russia, constructed by the local crime lord Nikolai Petrovich Sutyagin.
The house no longer exists, but at one time, the 13-story, 44-metre-tall (144 ft) Sutyagin House was said to be the tallest wooden house in Russia or even the world.
Starting in 1992, Mr. Sutyagin and his family constructed the house over 15 years without formal plans or a building permit.
Sutyagin only intended to build a two-storey structure — larger than those of his neighbors to reflect his position as the city’s richest man.
