This is my 1:1 scale reconstruction of the Monastery of Pantanassa in mystras/sparta as one of the first of a series of builds from the temporary roman capital of mystras.
You heard that right mystras (literally overlooking sparta on mt taygetos) was temporarily the capital of the eastern roman/byzantine empire during the 4th crusade and when Constantinople was under the control of the latin empire established there. During this time mystras and nicaea rose in prominence and flourished as capitals of various byzantine splinter groups but mystras led by michael viii palaiologos was the only one successful in retaking constantinople

some history

The Pantanassa, the katholikon of a monastery, is a foundation of the
protostrator and mesazon John Phrangopoulos, a high-ranking functionary
of the military and administrative hierarchy in the despotate. The name
and position of the donor are mentioned in an inscription in the western
gallery, and in monograms carved on the impost of a column of the nave.
The date of the church’s construction, 1428, was recorded in a dubious
lost inscription that had been read by the abbot Fourmont in 1730.

The design of the Pantanassa Church follows the Mystras architectural
type, which developed in the churches of Mystras after its inaugural use
in the Hodegetria of the Brontochion Monastery.
While the architecture imitates that of the Hodegetria, the corner
domes barely project above the roof. Festoons decorate the apses,
pointed arches frame some windows; and further signs of Frankish
influence can be seen in the prominent bell tower. As is common for most
Mystras churches, some of the reliefs are reused, while others are
works contemporary with the construction of the building.

The organization of the iconographic program and the choice of the
individual figures are modeled after those of the church of the
Hodegetria, while the iconography of the Christological scenes is
related to those of the Peribleptos.
Participating in the decoration were at least three painters, most
likely of metropolitan origin, for their works exhibit exceptional
quality. They brought their knowledge of the most up-to-date trends in
the capital to their painting in Mystras’ major fourteenth-century
monuments, the Hodegetria and the Peribleptos churches.

If the exterior of the church of the Pantanassa shows an acceptance of
Western decorative elements on a Byzantine structure, the wall paintings
adhere to a purely Orthodox tradition. With solid roots in the
classical past, and in accord with the humanistic tendencies of the era,
the painters of the Pantanassa experimented with the rendering of
landscape and space and gave essential roles to color and light,
revealing their preoccupation with innovations also found in the
contemporary art of the West. This Renaissance spirit and innovative
questioning indicate the potential of an art form whose development was
abruptly halted by the Ottoman conquest.
