Hanh Thong Tay Church is located at 53/7, Quang Trung Street, Ward 11, Go Vap District, Tp. Ho Chi Minh in the shape of light, elegant with white and gray colors. This is a rare building in Byzantine architectural style, while most churches in Vietnam are designed in Gothique or Romanesque style. The distinctive feature of the Byzantine architecture in the church is shown by the only semi-hemispherical dome-shaped round tower at the end near the sanctuary (the type of centralized space). Above the dome is a small spire-shaped tower for light. Walls outside the church are slippery patches, only decorated with simple patterns and reliefs of plaster. Beneath the church bell tower built of boulders, inside is a set of bells featuring three different three-syllable ones. This bell set was cast by the famous French bell maker Paccard in 1925.

Highlights are the arched dome along the length of the church assembled from square pattern reliefs. Along the sides are rows of columns with sophisticated patterns on the head. Between the columns also used the form of domed structure, hanging ceiling fans from the French era. Interspersed among colorful stained-glass windows are iridescent golden reliefs that portray each of the tribulations that Jesus has experienced. Especially, there are three altars on the sanctuary which are sculpted very elaborately from Italian gold marble. Around the walls and ceiling are decorated with many mosaic paintings (Mosaic school). The most impressive is the picture of the Lord Jesus drawing a picture of the Virgin Mary and St. John at the arch.
