The interior of the refectory is covered with frescoes dating to the year 1496/7, according to a relevant inscription, while in some places, there are later layers and over-paintings. When the original frescoes were made, the present-day wooden roof had already been constructed. This places the date of the roof at the end of the 15th century, making it a rare, reliably-dated example of wooden roofing, which has preserved the construction characteristics of the era. Most of it remains in good condition, although some repairs had been made in the 17th-19th centuries but were replaced in the 1970s decade.
