Tourism is widely recognized as one of the world’s oldest and fastest-growing industries, with deep historical roots in the cultural travels of early European elites during the seventeenth-century Grand Tour. Over time, tourism has evolved from an elite cultural practice into a global phenomenon that plays a critical role in socio-economic development, cultural exchange, and place identity. Central to this evolution is cultural heritage, which constitutes a major attraction for tourists and a vital resource for destination competitiveness. This study examines the significance of cultural heritage in shaping tourism development, emphasizing how the preservation and promotion of tangible and intangible heritage assets can enhance destination appeal and sustainability. It argues that safeguarding cultural heritage not only strengthens cultural identity but also stimulates tourism growth, generates employment opportunities, and supports local economies. By situating cultural heritage within contemporary tourism discourse, the paper highlights the need for integrated heritage management strategies that balance conservation with responsible tourism development.
