Cave 24 is like Cave 21, unfinished but much larger. It features the second largest monastery hall (29.3 × 29.3 m) after Cave 4. The cave 24 monastery has been important to scholarly studies of the site because it shows how multiple crews of workers completed their objectives in parallel. The cell construction began as soon as the aisle had been excavated and while the main hall and sanctum were under construction. The construction of Cave 24 was planned in 467 CE, but likely started in 475 CE, with support from Buddhabhadra, then abruptly ended in 477 with the sponsor king Harisena's death.
