The floor of the tower is octagonal, with irregular sides, and two rooms were known; a ground floor, on which was located a main floor that gave access to the upper deck closed by a crenellated parapet. The restoration works have discovered a lower space that served as a well or water collection site.
Once the thesis on the Roman origin of the walled enclosure of Seville has been rejected, the hypothesis about the Almohad character of the wall tends to be followed.
Currently, the hypothesis based on recent archaeological research is defined with more certainty, that the last walled enclosure in Seville corresponds to a first work undertaken by the Almoravides partially modified in the Almohad period.
The dating of the Almoravid wall of Seville is approximately around 1125. The last addition of the wall of the Arab Seville, except for the palatial area of the South flank of the city, takes place in the late Almohad period with the construction of the Tower of the Gold and the Walls that united the coracha with the rest of the city towards 1220. The following year the barbican and the moat were built. In addition, the walls of the total perimeter of the fence are overhung to leave it at the same height as the new Almohad area built on the river bank by the side of the Torre del Oro.
The Tower of the Silver was inserted in the stripping that delimited the apple of the House of the Currency.
The walls of Seville remained practically as the Arabs left it until the end of the Middle Ages. From this moment, when the walls cease to have meaning as a method of defence, they adapt spontaneously to other uses.
Since the bans on building were no longer supported by the wall when they lost their defensive utility, their walls served as support for a multitude of houses, warehouses and other buildings.
From the beginning of the 16th century, the tower was surrounded by houses, warehouses and warehouses, progressively losing its strategic definition and its visual spectacularity. In this sense the Torre de la Plata appears included in the Corral de Segovia without any use, until the seventeenth century that was rented together with other adjoining buildings.
Until very recent times it served as a dwelling and the buildings attached to it made it forget its protagonism of other times, only glimpsing of its elevation the platform of battlements standing out barely of the village.
The lower floor has an octagonal configuration, following the exterior delimitation of the watchtower. It is covered by a remarkable vault of ribs with a primitive gothic aspect, arranged in eight elements that support as many ribs of rectangular section, with slightly chamfered edges. They start from simple pilasters with no less simple imposts and come to join all in a polygonal key.
The primitive stairway is demolished and the upper floor is accessed through the house attached to the tower by a staircase belonging to this later construction.
A similar arrangement can be seen on the upper floor, except that here the vault of ribs is reinforced by a series of iron braces that start from a band of the same material, which transcends to the outside. In this case the original staircase is conserved, structured in two sections supported on the interior walls, with curious brick discharge arches, somewhat banked. This staircase leads to the upper roof.
In the exterior brick rigging, in the upper zone, the line of a filled battlement is observed in a possible tower screed.
Probably in its origin the walls of the tower were covered by a whitewashed plaster, hence the name of Torre de la Plata with which this watchtower has always been known.
As for the wall of preserved wall that part of it, is integrated into the whole of the Mint and was part of the coracha that linked the Torre de la Plata with the Torre del Oro, through a smaller tower intermediate.
Particularly worthy of particular consideration are the houses attached to the tower facing Santander Street, which are a valuable example of the new architectural currents introduced in Seville by the Italian Mannerist masters, at the beginning of the 17th century, such as Vermondo Resta, who was its author.
Currently, its rehabilitation is being restored and planned with functionality not yet determined.
