Siza has organized the program of the Anastasis church with a particularity, a vertical distribution that allows to free itself from the orientation of the volume. The sequence of circulation is organized after the modest covered entrance, between the two rectangular volumes. Once inside the monolith, the ground floor surprisingly accomodates the administrative and social functions. It is necessary to go up, to rise, to reach the ceremonial space. It is built in the cylinder, 45 degrees offset from the building, isolating itself from the outside, as if centred on itself.

The minimalist architecture of the church reinforces the idea of spirituality and simplicity. Although the church is a concrete sculpture whose forms connect the building to the city, the absence of a breakthrough allows for concentration, recollection, prayer and isolation. Particular attention is paid to the ceremonial space, which is generously illuminated by controlled indirect zenithal lighting. The daylight bounces and is reflected on the curved concrete and marble walls, allowing diffuse lighting. The space can accommodate nearly 130 worshippers in this particular configuration. Finally, the sacristy is located on the upper level, using an enclosed staircase, defining a more private access to this part of the program.
