The external façade is in Baroque style and this important architectural expression is not present in any of the other monuments in Putignano. The front stands majestically and imposing on the small square which takes its name from the church itself.
The entire front elevation of the church of Santa Maria la Greca, curvilinear, divided into three vertical compartments by a pair of pilasters and interspersed with a noble horizontal cornice that divides from two horizontal orders.
The portal placed in the lower order is framed by a quick shaped porch, supported by Corinthian columns that rest on high plinths and at the top of the central part there is an empty aedicule in which it was certainly the intention of the designer to place some sacred image . On the two sides we find other secondary access doors on which oval windows are highlighted.
In the second order at the top there is a large shaped window, which acts as an internal light point, above which the pediment of the facade rises, decorated with cornices and elegant scrolls.
