Xa Phin Mountainous Village in Ha Giang Province, northern Vietnam is home to many ancient stilt houses adorned with a picturesque layer of moss.

Xa Phin, which is home to the Dao people, an ethnic group, is anchored in the midst of the Tay Con Linh Mountain Range.

Every stilt house in the village boasts a roof adorned with a lavish display of up to 10,000 intricately arranged palm leaves.

It takes seven or eight years to have a house roof covered with moss, said Dang Van Hiep, a local of Xa Phin Mountainous Village.

The thicker the layer of moss on a house roof gets, the older the house is, he said.

The moss turns yellow and dry in the summer, while it becomes green and develops well in the winter.
