For arrangement of the church surroundings the Designers anticipated placement of stone cubes in order to decompound the space. On the cubes they shaped important persons, events or cultural facts from Gacka and Otočac region. Chakavian Parliament of Gacka region suggested giving sculptor content to those stone blocks by making each block one of the glagolitic letters. Following that thought, 30 sculptures were created, which tells a story in stone, from the beginning of the 9th century, ending with the 21st century.
A well know sculptor from Pula, Šime Vidulin, who was given complete freedom when choosing the artists, set a goal to make the colonies international, and to bring new (other) artists every year.
The sculpting colony took place at the end of July 2010 when first eight blocks were done. Respecting the set goal, Vidulin brought academic sculptors from abroad: Janez Pirnat from Ljubljana, Gabriele Gotolli from Verona and Toni Marić from Mostar. Apart from him, the domestic forces were represented by academic sculptors Mate Čvrljak from Labin and Sandra Nejašmić from Postira on the island of Brač, as well as his sculptors of confidence, Janko Mošnja from Pula and Marčelo Starčić from Kanfanar. Đildo Bonaca from Pula helped with the engraving of texts. Eight glagolitic letters (a, b, v, g, d, e, ž) and the following characters were engraved in the first eight motives:
- The Duke Borna (-821) – the Duke of Gacka people
- The Baška Tablet (1100) – the oldest monument written in Croatian and the first mention of Otočac
