In he rebuilt the Chora Church, originally restored by his maternal grandmother, Maria Doukaina. The Chora was also the initial location of his tomb, before he had it transferred to the Kosmosoteira. The Chora Church contains the only securely attested depiction of Isaac, in a "deesis" mosaic that dates to the church's restoration by Theodore Metochites in the early 14th century, but which most likely faithfully reproduces the original decoration of the church after Isaac's reconstruction. As historian Kallirroe Linardatou points out, in the mosaic, Isaac bears a crown that exceeds the simple circlet usually borne by a "sebastokrator" by being richly decorated and featuring a domed cover, deliberately hinting at imperial attributes. He also commissioned a number of icons, either mentioned in the "typikon" of the Kosmosoteira or known through the epigraphs associated with them.
