Fragments of low-relief sculpture with pre-Romanesque motifs of flowers, three-ribbon interlace, crosses, etc. covering the altar, the ciborium and column capitals were found in the Church of St. Archangel Michael in Martinići. All three naves of the church were decorated with liturgical furniture. The remains of the ciborium, placed above the altar, are similar to those found in Kotor and Ulcinj dated to the 9th century, with motifs of crosses, octagons, stars and oak and ivy leaves. It also shows a resemblance to the decoration found in Zachlumia and Terbounia, which led researchers to believe that masters working on the Adriatic Coast were also active in the heartland of the Balkans.
The rood screen (chancel screen, cancellum) is still to be seen in situ (its bases) and numerous fragments decorated with various motifs of plaited plastic remained. The lower zone of the chancel screen of the middle nave had an inscription, of which fragments remain in Latin and Greek. The Greek text that was on the left side was reconstructed by Vojislav Korać (based on the opinion of Sotiris Kissas) in two variants:

1. +.Ο Θ (EO)C TH ΠΡΕC (BEIA).....E TON (Π)ETR(0N)I...
2. + Ο Θ (EO)C TH ΠΡΕC (BEIA)... (ΦYΛATT) E TON (Π)ETR(0N)I...

The preserved part of the Latin inscription reads: + (MICH)AEL ET IOH(AN)E DIE..
....ET GLORIA BEATO MIXAEL AR(CHANGELO):.. .....N.......LIN

Remains of the plastic in Martinići are kept in the Regional Museum of Danilovgrad (Montenegro).
