Rucellai Sepulchre, Renaissance chapel in San Pancrazio Church, Florence, Italy.

The Rucellai Sepulchre is a small funerary chapel inside the Rucellai Chapel of San Pancrazio in Florence, designed by Leon Battista Alberti. Its exterior walls are covered with thirty square marble inlay panels in white and green marble, each with a different geometric or vegetal pattern. A low door leads to the interior, whose walls and vault are entirely frescoed, attributed to Giovanni da Piamonte.

Leon Battista Alberti designed this chapel in 1458 for Giovanni di Paolo Rucellai, a wealthy merchant and art patron. It was completed in 1467 and became an important example of Renaissance architecture in Florence.

The chapel's name comes from the Holy Sepulchre in Jerusalem, which it imitates at reduced scale. Each of the 30 exterior marble panels carries a different white-and-green geometric or vegetal pattern, and four heraldic emblems stand out on the sides: Giovanni Rucellai's sail, Cosimo il Vecchio's mazzocchio with three feathers, Piero de' Medici's diamond ring with two feathers, and Lorenzo il Magnifico's three interwoven rings.

Visitors reach the sepulchre through the Marino Marini Museum located at Piazza San Pancrazio. The space is small and rewards taking time to study the details of the marble inlays.

Each side of the exterior carries a heraldic emblem among the marble panels: Giovanni Rucellai's sail filled with wind and loose rigging, Cosimo il Vecchio's mazzocchio with three feathers, Piero de' Medici's diamond ring with two feathers, and Lorenzo il Magnifico's three interwoven rings. The 16.8 cm letters of the inscription match those of the Roman tomb of Cecilia Metella.
