In the first half of the XVIII century the monastery was already waiting for the construction of a new bell tower to replace the old, which by that time no longer fit into the architectural ensemble of the monastery. For a long time the monastery led a dispute with the Empress Anna Ioannovna over the location of new construction. The Empress ordered to put the steeple in the centre of Cathedral square, but, in the opinion of the architects I. F. Michurin and I. Schumacher, this place was chosen badly, as the tallest building would break views of the beautiful cathedrals. The architects proposed to shift the bell tower to the Northern part of the square on the site of the old Refectory. This was done, but after the death of Empress Anna Ioannovna.

The first project of the tower was pretty standard for the times: a three-tiered rather cumbersome in its proportions the building. Construction began in 1741, under the leadership of Michurin and his assistant Igor Zhukov. They had no time to finish the bell tower. In 1747 masters withdrew in Kiev for the construction of St. Andrew's Cathedral. The construction of the bell tower took on D. V. Ukhtomsky. He brought the Empress Elizabeth Petrovna on the project to increase the height of the bell tower. The project was approved, and in 1753, the building continued its growth. However, work on the decoration of the facades lasted another 15 years. In 1770 the monastery saw his new belfry be what it can observe and we in our time.

Bottom large bunk quadrangle with a powerful base carrying a pyramid of four growing up open arched belfries. Art historians call the Baroque fundamental to the bell tower. Fifth tier is crowned with a gilded crown and a four-meter cross with restraint chains on him. Between the third and fourth tiers chimes are connected with eight bells, which is still preserved. First clock was installed in the monastery in 1784. They were made by Tula master Ivan Kobylin. In 1905 they were replaced with those that show the monastery and today. Carefully chose the color for the bell tower. Stopped at sky turquoise paint.

The total height of the bell tower is 88 m. Lavra bell tower is the highest among the bell towers of Russia. Forty-two bells were created under her to become. In 1759, still under construction on the tower raised Russia's largest ringing — "King of". Its weight was estimated at 4,000 tons (64 tons). Next to it on the lower tier of the belfry was located two more festive jingle: "Godunov" and "Kinohi" bells weighing 1850 and 1275 pounds. All three bells among others were lost in the 1930-ies, when there were persecutions of the Church. The process of destruction of these large bells shook the Soviet writer Mikhail Prishvin. In his memoirs he describes pain their death, if it were a living creature. "It was the spectacle of a public execution", he wrote in his diary. After that survived only 17 bells. Among them, "Nikon" casting 1420 is one of the oldest bells in the monastery — and "Winches" work Chohova 1594. In 2002 began the restoration of the bells of the first tier of ringing. "Blagovest" and "Firstborn" has replaced "Godunov" and "Kornoukhovo". One year later, the cast and the main bell of the Trinity Sergius Lavra instead of lost "the King". For the first time the 72-ton bell rang on the day of the Holy Trinity may 30, 2003.
