Sri Lanka is a land of great cultural diversity. Religion pervades many aspects of life and constitutes a basic element of this diversity. Buddhist and Hindu temples, as well as mosques and churches, with their own colourful rituals, are the most readily visible features of the cultural landscape. Varying degrees of colonial impact, modernizing influences, and wealth and income add other shades to this cultural mosaic.

Religion plays an important role in Sri Lanka ; a revival of Buddhism was associated with the rise of Sinhalese nationalism. Most public holidays are based on religious festivals. The annual torchlight temple procession, or Perahara, in which ornamentally covered elephants and hundreds of dancers participate, draws thousands of devotees. Pilgrimages also play an important role here. The most important pilgrimage is to the top of Adams Peak . It is believed that Adam and Eve lived here after they left the Garden of Eden. Buddhists visit a rock on the peak that they believe contains one of Buddha's footprints. Another important pilgrimage is to the Temple of the Tooth in Kandy , where one of Lord Buddha's teeth is enshrined.

In architecture, sculpture, and painting, Sri Lanka 's traditions extend far back into antiquity. The remnants of ancient works restored and preserved at archaeological sites, while reflecting Indian influences, also bear testimony to the inspiration derived from Buddhism. Classical literature, too, presents a blend of stylistic influences from India with Buddhist themes. Since the beginning of the 20th century, with the literati being exposed to European literature, local creative writing has acquired greater diversity in style and has become more secular in content.
