Symphonies in Wood, Basalt, and Forest Stone: The Traditional Kerala Spires of Vadakkunnathan, the Hidden Kadamba Shrines of Tambdi Surla, and the Erotic Ruins of Madan Kamdev

Across the diverse landscapes of India, ancient and medieval temples stand as monumental lithic books, preserving the mathematical, geological, and artistic heritage of forgotten eras. These structures are not merely religious sanctuaries but peaks of structural engineering, exhibiting advanced design principles tailored to their local climates and geologies. By exploring three unique masterpieces—the timber-sloped Vadakkunnathan Temple in Thrissur, the basalt-carved Mahadev Temple in the jungles of Goa, and the rediscovered stone ruins of Madan Kamdev in Assam—we trace the incredible diversity of Chera, Kadamba, and Kamarupa dynasty architecture.

🏛️ Sacred Wood and Circular Spires: Vadakkunnathan Temple of Thrissur

Nestled in the heart of Thrissur, Kerala, the Vadakkunnathan Temple is a classic exemplar of Kerala-Dravida temple architecture. Commissioned during the height of the Chera Perumals of Mahodayapuram (circa 8th to 9th centuries CE), the temple represents a unique architectural adaptation to the heavy tropical monsoons of southwestern India. Rather than the soaring stone gopurams seen in the neighboring Tamil plains, the temple’s exterior is defined by low, whitewashed laterite stone walls and majestic, double-storied gateways with steep, sloping tiled roofs. The entire complex is situated within a spacious nine-acre sacred compound, acting as a serene sanctuary that stands in stark contrast to the surrounding urban landscape.

The centerpiece of the temple is the principal sanctum (srikovil), dedicated to Shiva. Unlike standard rectangular shrines, this srikovil features a circular plan (vatta srikovil) topped by a towering conical roof covered with interlocking copper plates. This design, which distributes weight evenly, is supported by a ring of inner wooden pillars and radial beams. The timber ceilings and brackets are adorned with intricate wood carvings representing episodes from the Puranas and Mahabharata, reflecting Kerala's peerless carpentry tradition. The inner sanctum walls also preserve outstanding mural paintings from the 16th and 17th centuries, including the dynamic multiphased Nataraja and the grand Gajendra Moksham murals, which showcase the fluid lines and natural pigment palettes of traditional Kerala painters.

According to local lore, the main deity inside the sanctum is a massive mound of ghee (Ghee Lingam), formed by centuries of daily ritual offerings (abhishekam) of ghee. Under the heat of the tropical climate, the ghee never melts and has solidified over generations into a shimmering, smooth structure rising several feet high. Historically, the temple was governed by a powerful assembly of local Brahmin families (sabhayars), whose decisions were recorded in medieval Vatteluttu inscriptions on the temple bases. These epigraphic records detail land endowments, administrative rules, and the strict codes of conduct governing the temple's daily operations, offering historians a window into the socio-political structures of early medieval Kerala.

🗿 The Basalt Survivor of the Western Ghats: Mahadev Temple of Tambdi Surla

Deep within the dense, tropical forests of the Bhagwan Mahavir Wildlife Sanctuary in Goa stands the Mahadev Temple of Tambdi Surla. Built in the late 12th to 13th centuries CE, it is the sole surviving structural stone temple of the Kadambas of Goa. This dynasty ruled the maritime trade routes of the west coast under the suzerainty of the Western Chalukyas and Yadavas. The temple’s remote jungle location is the primary reason it survived the destructive campaigns of the Bahmani Sultanate and the subsequent Portuguese Inquisition, which saw the systematic demolition of almost all other Hindu temples in Goa's coastal plains.

The construction of the temple is a feat of geological engineering. It is built using fine-grained, dark grey weather-resistant basalt stone. Basalt is not found in Goa’s coastal soils; the stones had to be quarried and transported over the steep Western Ghats, likely from the Deccan plateau. The layout is a hybrid Vesara style, consisting of a sanctum (garbhagriha), an intermediate vestibule (antarala), and a pillared assembly hall (sabhamandapa). The pillars are beautifully turned, featuring delicate floral and geometric bands, with detailed reliefs of Shiva, Vishnu, Brahma, and Ganesha carved on their bases. The sloping, stepped roof of the mandapa is composed of flat stone slabs designed to mimic traditional timber tiles, a structural choice made to shed Goa’s torrential monsoonal rains.

Over the sanctum rises a three-tiered tower (shikhara), constructed in the Kadamba-Nagara style. This style features horizontal stepped bands adorned with niches containing beautifully detailed relief carvings of Hindu deities. The center of the mandapa ceiling is carved with a gorgeous, deep-relief lotus medallion, a signature element of Kadamba-Yadava art. The temple remains a living monument, where the quiet sound of the Surla River flowing nearby blends with the ancient basalt stones to evoke a profound sense of antiquity and archaeological mystery.

🔱 The Forgotten Friezes of Kamarupa: The Ruins of Madan Kamdev

Located on the Madan Hill in Kamrup district, Assam, Madan Kamdev is one of the most enigmatic archaeological sites in Northeast India. Dating to the 10th to 12th centuries CE during the reign of the Pala dynasty of Kamarupa, the site comprises the ruins of a complex of twelve to fifteen stone temples. This dynasty, which ruled the Brahmaputra Valley, fostered a distinct regional art style that blended early medieval Nagara architectural elements with Eastern Indian Pala-Sena stylistic features. The entire complex lay forgotten under dense jungle overgrowth for centuries, partially destroyed by the devastating 1897 Assam earthquake, until it was rediscovered and excavated by the Archaeological Survey of India in the 1970s.

The principal shrine of Madan Kamdev is dedicated to Kamadeva (the Hindu god of love) and his consort Rati. The ruins feature a wealth of highly expressive, sensual, and erotic stone carvings, earning it the moniker "the Khajuraho of Northeast India." These sculptures, carved with high relief from locally quarried sandstone, depict celestial nymphs (apsaras), mythical composite beasts (yalis or vyalas), warriors, elephants, and intricate floral scrolls. The carving style is characterized by rounded limbs, expressive eyes, and dynamic postures, demonstrating a high degree of artistic sophistication.

Architecturally, the temples were constructed using dry ashlar masonry. The builders carved interlocking stone blocks that were fitted together using iron clamps and dowels, completely avoiding the use of mortar. This technique allowed the structures to withstand the seismic movements of the region for centuries, though the sheer force of major earthquakes eventually brought down their superstructures. The remaining stone slabs, decorated columns, and monumental lintels lie scattered across the green forest floor, offering a dramatic, romantic picture of an ancient empire’s artistic high point frozen in time.

📌 The Bottom Line
