Đá Đen Temple, Suối Hai Commune

Đá Đen Temple is a traditional architectural work, built to meet the village community's cultural and religious needs, and belongs to the temple-type belief category.

+ Based on the artifacts in the relic and field documents such as: the system of statues at the relic, the great characters, horizontal panels, parallel sentences, and wooden incense tables bearing the artistic style of the Nguyễn era.. Đá Đen Temple worships Mrs. Đinh Thị Điên (also known as Đen) or Lady Chúa Đá Đen – the mother of Saint Tản Viên Sơn

The temple architecture includes the following items:

*Lầu thờ Bà chúa Đá Đen: The Lady Chúa shrine is a modest architectural unit, built on the top of an artificial stone mountain higher than the surrounding structures. The shrine is built in the Nhất character layout, one compartment, with a roof covered in Vietnamese tiles, carrying traditional architectural style. This is precisely where the bronze statue of Lady Chúa Đá Đen and artifacts and objects such as long ngai, đỉnh, bát hương, .... in the artistic style of the 20th century are placed

.* Mẫu Temple: includes the front hall and rear sanctuary, surrounded by a garden courtyard and auxiliary works such as lầu cô lầu cậu, guest house, temple well…

-Front hall: From the temple gate, across a fairly large courtyard, one reaches the Front Hall. The Front Hall is a horizontal building with a three-compartment structure, with a curved đao roof, roofed with ri tiles. The ridge is decorated with dragons facing the sun. The đao corners of the Front Hall were originally elaborately molded and painted, but have deteriorated over time. Inside, corresponding to 3 compartments and 2 side bays are 4 sets of trusses on 4 rows of column bases. The trusses of the main compartments are structured alike in the vì kèo style. Especially here, the nề ngõa technique imitates traditional architectural style and structure.

The hidden-column technique in this front hall creates a corresponding load-bearing structure of the two main columns with hidden bases, which is rarely seen in other relics. The trusses of the two side bays are also made in the vì kèo style; the components here were mainly left plain by the craftsmen without decoration, leaning toward durability.

- Rear sanctuary: The rear sanctuary is built connected to the central compartment of the front hall. The rear sanctuary is also built in a three-compartment style, roofed with ri tiles. From the outside, the roof of the rear sanctuary of Đá Đen Temple is designed softly. Overall, the architecture of Đá Đen Temple basically retains traditional features, bearing the appearance of a temple from the late 19th and early 20th centuries.

At Đá Đen Temple, in a year, in addition to the death anniversary on the 19th day of the 9th lunar month, the spring festival, the lunar calendar's first and fifteenth days, and other major days such as the anniversary of the birth and the day of transformation into a saint, solemn ceremonies of veneration are also held, attracting pilgrims from all directions.
