Over the centuries the church has undergone various restoration work and has been enriched with decorations. Between the late 19^th century and the early 20^th century, tempera decorations were added. The simple and harmonious 19^th century façade with its main door and windows entices passers-by to venture in. Inside, the church is divided into two main spaces, divided by an arch supporting the vault. The entrance area lies beneath a dome decorated with angelic figures while the presbytery preserves the painting “La Cacciata dal Paradiso Terrestre” (The Expulsion from Paradise). On the back wall is the 18^th century effigy of Our Lady of the Rosary by Domenico Carella. A large gold-coloured wooden crown and fifteen oval paintings attributed to Gaetano Quercia narrate the mysteries of the rosary. Every year on the last Sunday of September, Grumo Appula gathers in prayer and devotion. The festival of the Holy Rosary transforms the church into the beating heart of the community, a vivid memories of centuries of history, art and faith. It is capable of uniting generations, protecting traditions and keeping hope alive in the hearts of the inhabitants of Grumo, testament to a spirituality which transcends time and continues to inspire.
