Holy Trinity Monastery is the richest treasury of the cultural and spiritual life of the Orthodox Serbs from the Middle Ages to the present times.

During a period of time in the history, traditional costumes displayed in the ethnological department of the Heritage Museum Pljevlja were carefully preserved in the monastery.

The differing traditions are skilfully harmonized and this can be classed among the finest products of sixteenth century Serbian goldsmith's work, because of its precise craftmanship and subtle proportions.

The accounts given by Rudolf Hilferding and Sava Kosanovic show that the nave and the sanctuary were decorated in 1595 by Father Strahinja of Budmilje.

The miniatures in Gavrilo's Psalter were the work of Jovan Kyr Kozma, considered one of the greatest Serb painters of the 17th century.

One of them represents the Nativity, dated to the 1570s and attributed to the prominent Serbian icon painter Zograf Longin of Peć, who also painted frescoes at Visoki Dečani.
