A new park which later became Alexander Park was established in the 1770s to the west of the Catherine Palace, and in 1792–1795 Giacomo Quarenghi built the Alexander Palace at the north-eastern border of the park for the future emperor Alexander I. In 1808, Alexander I merged the Tsarskoye Selo with Sofia and proclaimed it a town and the seat of Tsarskoselsky Uyezd.
In 1808, he appointed William Heste as the town architect, which post he held until his death in 1832.
Heste compiled a master plan for Tsarskoye Selo, with division into quarters and associated gardens and orchards.
Most residents moved from Sofia to Tsarskoye Selo and the former was converted to a residence of a military regiment.
By 1817, Tsarskoye Selo had 15 streets, 354 buildings and a population of 4,000.

The Catherine Palace suffered from the fire of 1820 and was reconstructed by the architect Vasily Stasov.
He also designed several buildings in classical style, namely the Manezh, Stable Building and Grand Orangery.
Between 1811 and 1843 a wing of the Catherine Palace hosted the Tsarskoye Selo Lyceum where Aleksandr Pushkin studied between 1811 and 1817.
Several historical objects were created in those decades including the iron Egyptian gates by Adam Menelaws.

The first public railway in the Russian Empire, Tsarskoselskaya Railway, was laid in 1837 and connected Tsarskoye Selo with the capital St. Petersburg.
Its length was about 22.5 km (14.0 mi) and the journey time about 40 minutes.
The prominent Catherine Cathedral was built in 1840.
The town was expanding and by 1855 had 44 streets, 10 churches, 400 houses, 8 military barracks, 3 hospitals and a female seminary.
Tsarskoye Selo was one of the most developed cities of Russia.
In 1887 it became the first fully electrified town in Europe, and by the end of the 19th century had a telephone network.

In 1905, the Alexander Palace became the main residence of the Nicholas II.
Here the royal family was held under house arrest after the February Revolution.
In 1902–1908 the town was equipped with the most advanced by the time water system with a separate sewer network and a water purification station.
By 1909 the town had 30,000 residents and 19 schools.
In 1910, an Imperial garrison camp was established to the north of the Catherine Palace, on the border of Alexander Park and the city.
It had a separate cathedral (Fedorovskiy Cathedral), a dining hall, and two hospitals, one for officers and one for soldiers.
The first bus route was opened in 1911, and in 1914 a powerful for the time 300-kilowatt wireless telegraphy station was built in the city.
Léon Theremin worked at that station in 1918–1919.
