Navalny was arrested, along with hundreds of others, and was jailed for 15 days after being convicted of disobeying a police officer. He said interference had prevented contractors from building a stage at the agreed venue.
Navalny announced the change less than 24 hours before the planned anticorruption protests across the country on the Russia Day holiday.
Moscow braced for a day of unauthorized protests on Monday after prominent opposition leader Alexei Navalny changed the location of an anti-corruption demonstration despite police warnings.
President Vladimir Putin vowed to punish people who broke the law after an estimated 60,000 people protested in March at anti-corruption rallies organised by Navalny that were mostly unsanctioned in 80 cities across Russian Federation, the biggest unrest in five years.
Although city authorities had agreed to a location for the Moscow protest, Navalny called for it to be moved to one of Moscow's main thoroughfares.

Electricity in his office was cut at around the same time as he was detained, briefly bringing down a live feed of nationwide protests, Navalny's spokeswoman said.
"Any provocative actions by the protesters will be viewed as threat to public order and immediately thwarted", the police said.
The anti-corruption activist and presidential hopeful has also called for protests in more than 200 cities across Russian Federation, which is celebrating a public holiday. More than 1,000 people were arrested at a similar rally organised by Navalny in March.
Navalny's website reported Monday that protests were held in more than a half-dozen cities in the Far East, including the major Pacific ports of Vladivostok and Khabarovsk and in Siberia's Barnaul. Russian opposition leader Alexei Navalny has called for anti-Kremlin protests on June 12, and activists in about 200 cities and towns are expected to turn out and demonstrate against government corruption. He focuses on corruption issues and has attracted a wide following through savvy use of internet video. It remains unclear too whether the Kremlin will let Navalny run for the presidency.
The wave of protests called by Navalny coincides with public holiday, Russian Federation day, with Putin handing out awards and holding a reception in the Kremlin. He is recovering after an assailant threw green dye in his face in April, the latest in a series of physical attacks.
