Architecture

Structure

The central section resembles the Almohad minarets' placement of a tower inside another tower, with its walls covered with plaster mortar.

Corridors and flights of stairs run between both the inner and outer towers and the space between girders lined by approaching brick courses.

The three superposed rooms are covered by a single pointed vault. The top section of the tower contains the belfry which again follows the Christian tower outline consisting of only one wall with a double row of open space.

Outer decoration

Within the outer decoration, more developed artistic maturity can be seen as compared to its predecessors. The ornamental brick wall sections are increasingly bigger, not only in its crossing mix of linear arches, but also in the four-element knots that form eight-pointed stars combined with crosses. Even zigzag strips are highlighted as they double in size.

The ceramic tiles follow the formal trend of the San Martín Tower, though El Salvador Tower shows a wider variety of smaller pieces.

The pottery was dyed both green with copper oxide and white with tin plate, then glazed with lead, thus displaying a wide range of shapes: square and rombic tiling, plates and discs, herringbone treads, graceful columns, eight-pointed stars.
