States Lane

States Lane is a north–south street in Brasília, Federal District that is a popular tourist attraction. Located in the Ministries Esplanade in front of the National Congress Palace in the Monumental Axis, this street contains 28 flags: the Brazilian national flag, the [Flag of the Distrito Federal (Brazil)|Federal District (Brazil)|flag of the Federal District], and flags of the 26 states of Brazil. It is a popular place for visitors to take pictures with the flag of their state.
The flags are changed on average every three months on dates such as the 1st day of the year, April 21st, September 7th, and November 19th. The local fire department assists in maintaining and exchanging the flags.
Despite being responsible for maintaining the street, the Secretary of State for Tourism of the Federal District does not know when the street was built nor its history or significance.
