In those days people usually built houses of wood. Sometimes there were fires in the city,but they were usually very small.1666 was the year of the Great Fire of London.
On Saturday, 2nd September,1666,there was a strong wind from the river and a big fire began. It started in the house of the kings baker, near London Bridge.
The bakers wife woke up in the middle of the night because the house was on fire. Soon the next house started burning and then the next and the next… The fire burns until Thursday. Many houses in London were burnt. The fire burnt for four days. More than 250 thousand people didn’t have home and more.
After the Great Fire people built a new city. It became larger and larger. By 1830, there were more than one and a half million people in London. The railways came and London became richer and richer.
