At the boundaries between Zografou and Ampelokipoi, at Georgios Papanderou Avenue, there is a small church, isolated from the tall buildings that surround it, for which limited information is available. It is the church of Agia Triada, which was in the past was mentioned as Panagia Goudi and was located in an estate of the medieval family of Goudi, from which the wider area also took its name.
We cannot date the church accurately, even though it is certain that its construction took place in the Middle Byzantine Period (9th – 12th century). In addition, it is not known whether it belonged to a monastery or if there were other modern buildings near it. However, it is mentioned in documents of 1773 and 1803.
In its initial form, it was a simple inscribed cruciform church, with a dome supported by two columns. Later, during the Turkish occupation of Greece, it was converted into a three-aisled basilica, which was roofed with arches. In the beginning of the 20th century it was in ruins and only the sanctuary and parts of its side walls remained, while there were no traces of its painting or sculpture decoration. In the years 1959-1961 the architect and archaeologist Anastasios Orlandos carried out restorations, which gave the church its present day form.
