Pallavas are most noted for their patronage of architecture, the finest example being the Shore Temple, a UNESCO World Heritage Site in Mamallapuram. Kancheepuram was capital of the Pallava kingdom. The Pallavas who left behind magnificent sculptures and temples, established the foundations of medieval South Indian architecture. They developed the Pallava script from which Grantha ultimately descended. The Pallava script gave rise to several other southeast Asian scripts. Chinese traveller Xuanzang visited Kanchipuram during Pallava rule and extolled their benign rule.
