During the reign of Vlad the Impaler (1456 - 1462, 1476) the Royal Court amplified itself through many constructions. The most important is the one of the surveillance and defence tower, known under the name of "Chindia Tower".

We don't have any informations about new constructions from the 16th century, when the rulers used mostly the Bucharest residence.It is possible, though, that some of the repair and improvement works may be carried out by Neagoe Basarab.

At the end of the 16th century, a series of fortification and construction works were initiated. Their promoter was Petru Cercel (1583 - 1585), who built a new palace, the Royal grand church and the first aqueduct and "the Royal Gardens" on the outside, towards the Ialomita river.

During the first Turkish occupation from 1595 and the liberation campaign lead by Mihai Viteazul, the Royal Court burned and suffered damages. Other depredations made by the troups of Gabriel Bathory, Prince of Transilvania followed.

During the rule of Matei Basarab (1632 - 1654) a new age of prosperity for the Court of Targoviste was registered. The royal houses were repaired, the enclosure wall was doubled. A "Turkish" bathroom was raised for the Court's needs right beside the palace, towards the Ialomita riverside. The aqueduct system was amplified at the same time.

New cloudy times rise in the middle of the 17th century, culminating with the order given by Gheorghe Ghica, ruler of the Romanian Country to demolish the walls of the Royal Court, considered by the Sultan to be the resistance core of the anti-Otoman battle.

The Royal Court saw a last blossoming period during the rule of Constantin Brancoveanu, which took a series of measures to renew the old royal residence. During this period the Royal Houses were partially remade, joining the two existing structures. The stone pavilion, the houses of the "iazagiu" (military guard) and the "coconi" (the royal offsprings) were built inside the Court, on the south side. Petru Cercel's church was adorned with a new temple and a new painting (1698), preserved until today.

After the tragic death of the waivode and its sons in Constantinopole in 1714, the Royal Court was abandoned and started decaying, becoming, in time, a source of construction material for the inhabitants of the town.

The 20th century beginned with the first substantial renewal of the Royal Court made by the Historical Monuments Committee during 1907 - 1910. Between the two world wars, Virgil Draghiceanu, under the guidance of Nicolae Iorga, conducted the works of partial liberation of the ruins, revealing also the walls of the chapel-church. During that age the walls of the bathroom and the palace were consolidated and protected, process which was repeated after the earthquake of 1940.

In the last decades, the works of archaeological and architectural research were continued and many measures of protection and renovation were took for the buildings in this ensemble.
