One distinctive feature of the ethnic minority groups in Vietnam is the traditional stilt houses, known as "rong" in the Central Highlands. These stilt houses are significant communal structures, serving as both living spaces and communal halls. The Bana, Xedang, and Giarai people in the Central Highlands are known for building these large stilt houses, which are characterized by steep, tall roofs and a balcony in front. These houses are well-suited to the flood-prone plains and steep mountain slopes, making them popular among many of Vietnam's 54 different ethnic groups. Stilt houses not only provide shelter but also serve as spaces for communal activities, worship, and traditional tasks like weaving and embroidery. The traditional stilt houses reflect the unique cultures of Vietnam's diverse ethnic groups and complement their natural surroundings.

One significant feature of ethnic minority groups in Vietnam is their unique architecture, particularly evident in their traditional stilt houses. Stilt houses are elevated structures built on wooden or bamboo stilts, often with a thatched roof. These houses serve multiple purposes, including protection against flooding, wild animals, and pests. Moreover, the elevated design helps to keep the interior cool during hot weather and dry during the rainy season.

The communal house, another distinctive feature, holds great cultural and social significance within ethnic minority communities. It serves as a gathering place for various communal activities, such as meetings, ceremonies, and celebrations. These houses are often beautifully decorated and adorned with intricate carvings and traditional motifs, reflecting the cultural heritage and identity of the community.

In addition to their architectural heritage, ethnic minority groups are also known for their mastery of terrace farming techniques. Terrace fields, meticulously carved into steep mountain slopes, allow them to cultivate rice and other crops in challenging terrain. These terraced landscapes not only showcase the ingenuity and resourcefulness of these communities but also contribute to the breathtaking natural scenery of Vietnam's highlands.

Overall, the stilt houses, communal houses, and terrace fields exemplify the rich cultural heritage and sustainable practices of Vietnam's ethnic minority groups, reflecting their deep connection to the land and their centuries-old traditions.
