St. Spyridon chapel is a single-naved church with a wooden roof, measuring around 35 square meters. The masonry, made of stone, has been plastered inside and out. The area of the chapel, before its revival by the Karoussos Archives, was left without a determined status concerning its Byzantine nature.

Further to the chapel's iconography, the imperative need to restore its Byzantine character, concerned the following issues:

​

- The shuttering of the roof, a typical example of Maniot architecture, was covered with suspended T&G ceiling.

-The chandeliers hanging from the vertical wooden beams, reduced the height, even more than the false ceiling.

- An unspecified stencil of a brown cross was all over the white walls, yielded a destruction in the space. 

- The wooden altarpiece, also painted brown, created a particularly heavy block for the scale of the chapel.

- Τhe chairs and the other liturgical objects, such as candle holders and trays covered with gold emulsion, foster the grotesque sense of the church, conflicted its very identity.

- The commercial copies of Byzantine icons subverted the value of the icons of the iconostasis (oil paintings) and even more of the pre-revolutionary frescoes of the sanctuary.

- The carpets covered the floor that functions as an aesthetic element of the space, decorated with a geometric Byzantine motif, taken from classical antiquity.
