Architectural Heritage Guide: My Son Sanctuary Tower Groups B, C, D and Hoi An Merchant Houses
Visiting My Son Sanctuary and Hoi An Ancient Town on the same day juxtaposes two UNESCO World Heritage architectural traditions: the mortarless fired-brick Hindu temples of Champa's central Groups B, C, and D, and the flood-resilient ironwood merchant homes of 17th-to-19th-century Hoi An. Knowing what structural details to look for turns a simple sightseeing transfer into a rich heritage walk.

Separated by just 42 km along the Thu Bon River valley, UNESCO World Heritage neighbours My Son Sanctuary and Hoi An Ancient Town represent two contrasting architectural masterclasses: the seamless, mortarless fired-brick temples of the Champa Kingdom at Tower Groups B–C–D, and the interlocking ironwood timber frames and yin-yang roof tiles of 17th-to-19th-century merchant shophouses. Booking a round-trip private car from Hoi An to My Son in the morning and returning for an afternoon architectural walk past the Japanese Covered Bridge, Tan Ky House, and Phung Hung House lets you compare thousand-year-old Hindu sacred geometry with maritime port engineering in a single day.
Architectural Comparison: 4 Heritage Monuments in My Son and Hoi An
Along the regional sightseeing route, the My Son temple complex lies within the My Son valley in Duy Xuyen District, Quang Nam Province, while Tan Ky House, Phung Hung House, and the Japanese Bridge sit in Hoi An Ward of Da Nang City. The table below compares construction techniques and visitor access across all four heritage landmarks:
| Heritage Monument | Era & Architectural Style | Core Materials & Building Technique | Key Details to Observe On-Site | Private Car Drop-Off & Access |
|---|---|---|---|---|
| Tower Groups B–C–D (My Son Sanctuary Core) | 8th – 13th Century (My Son A1 & Hoa Lai Champa styles) | Fired red bricks rubbed flush using organic Dau Rai tree resin, paired with carved sandstone lintels | Principal sanctuaries B1 and C1, gateway towers (Gopura), and long halls D1–D2 displaying sandstone reliefs | Private car parks at the My Son main gate; internal electric shuttles take guests to the B–C–D valley path |
| Tower Group G & Groups E–F (My Son Hillside) | 8th – 12th Century (Early to transitional Champa brickwork) | Terracotta reliefs carved directly into brick walls depicting Kala masks and Apsara dancers | Elevated hillside setting demonstrating modern international archaeological conservation methods | A gentle 300-metre shaded stone path walk from the central B–C–D courtyard |

| Tan Ky Ancient House (101 Nguyen Thai Hoc) & Phung Hung House (04 Nguyen Thi Minh Khai) | Late 18th – 19th Century (Hoi An port merchant tube-houses) | Ironwood (Go Lim) and jackfruit timber joined strictly by mortise-and-tenon joints without iron nails | Crab-shell ceiling trusses, central open courtyard (gieng troi), and historical flood-level markers on pillars | Easy walking loop along Nguyen Thi Minh Khai and Nguyen Thai Hoc while your car waits at the perimeter |

What Makes Tower Groups B–C–D the Architectural Heart of My Son?
Within the sacred basin of My Son, Tower Groups B, C, and D preserve the clearest layout of a royal Champa Hindu sanctuary complex:
- Sacred Tripartite Layout (Mandapa – Gopura – Kalan): Approaching Groups B and C from the east, visitors first pass through the elongated brick assembly halls D1 and D2 (Mandapa)—which now house museum-grade sandstone pedestals, Shiva reliefs, and Linga-Yoni altars—before stepping through the gateway tower (Gopura) into the central sanctuary courtyard (Kalan B1 and C1).
- Sub-Millimeter Mortarless Brick Joints: Champa builders ground kilned bricks together using organic resin extracted from indigenous Dau Rai (Dipterocarpus) trees. The resulting hairline joints prevent water penetration and plant roots from splitting the load-bearing walls across centuries of tropical monsoons.
Climate-Adaptive Engineering Inside Tan Ky and Phung Hung Ancient Houses
- Dual-Frontage Tube Layout Between Street and River: Tan Ky Ancient House opens onto Nguyen Thai Hoc Street for retail trade in front while its rear door connects directly to Bach Dang Street along the Hoai River where cargo boats once docked; a central open-air courtyard pulls cool river breezes through the timber halls and releases summer heat.
- Unrushed Exploration with a Round-Trip Private Car (ST-ROUTE-011): Booking Sun Travel’s Hoi An – My Son round-trip private car gives your party 3 to 4 hours of dedicated waiting time at the sanctuary so architecture enthusiasts can study the sandstone carvings at Groups B–C–D without a tour guide rushing the group.
