The Friday Gates, also known as the Friday Tower, are the main gates of the Kolomna Kremlin. They are located on the eastern side of the Kremlin between the non-existent Zastenochna Tower and the Pogorela Tower, leading to the road that goes to Vladimir and Kashira, now Zaitseva Street. These are one of the six gates of the Kolomna Kremlin, including the breach gates, and the only surviving passage tower out of four. The street Lazareva runs through these gates.

The Friday Tower likely got its name from the wooden church of Paraskeva Friday, which stood behind the Kremlin wall near the gates. Paraskeva Friday was considered the patroness of trade. By the 18th century, the church had fallen into ruin, and the gates began to be called Spasskiye, possibly due to the Spassky Monastery located three hundred meters southeast of the Kremlin wall, or because of the icon of the Merciful Savior Not Made by Hands that hung above the passage. However, this name did not take hold, likely due to the construction of the Friday Chapel in the 19th century.

According to the Inventory Book of 1578-1579, the tower at the Friday Gates housed 16 bronze and 74 iron cannons, 5500 iron balls, 17 poods of lead balls, 31 poods of zinc balls, cannons, "herbs" and 7 barrels of gunpowder. The gates consisted of a two-tiered tower and a drawbridge with battlements. The base of the tower is rectangular, 14 m wide and 22 m long. The passage arch of the gates is horseshoe-shaped, with grooves for the herds preserved. Under the tower was a vaulted passage connecting the fortress with the city in case of danger. The tower is executed in modest architectural forms, decorated with white stone details. Above the passage arches were bas-relief icons made of white stone. At the top of the tower hung an alarm bell.

The Friday Tower resembles the Spasskaya Tower of the Moscow Kremlin, especially its lower tier with the drawbridge. This similarity is confirmed by the presence of over-gate icons on both sides of the gates. The upper tier with a quadrangular roof gives the tower a resemblance to the Ivanovskaya Tower of the Nizhny Novgorod Kremlin, built fifteen years earlier but receiving its modern appearance after restoration in the 1950s. On the northern side, the Friday Chapel, built in the 1820s from brick and white stone in the classical style, adjoins the tower, replacing the former church of Paraskeva Friday. A minor update of the tower was conducted in 1826, and the first restoration under the guidance of A. M. Pavlinov took place in 1886 and 1906. The next restoration occurred in the 1960s, and the last one was in the late 1990s and early 2000s.
