Architecture of Kerala in the context of Christianity in Kerala

The Cheraman Juma Mosque is a mosque in Kodungallur, Thrissur district, in the state of Kerala, India. The mosque was built in 629 CE by Malik Bin Dinar though some scholars suggest a later construction date in the 14th–15th century. Due to these claims, it is often regarded as the first mosque built in India and the oldest mosque on the Indian subcontinent still in use. However, historical research has cast doubt on these claims, suggesting that the origin story may be fictitious or legendary rather than factual.

The mosque was built in the Kerala-Islamic traditional Vastu shastra architectural style, with hanging lamps, making the historicity of its date claims more convincing.

The Padmanabhaswamy Temple (Malayalam: [pɐd̪mɐnaːbʰɐswaːmi]) is a Hindu temple dedicated to Vishnu in Thiruvananthapuram, the capital of the state of Kerala, India. It is one of the 108 Divya Desams that are considered among the most sacred abodes of Vishnu in the Sri Vaishnava tradition. Adi Shankara had composed sacred hymns on AnanthaPadmanabha and it is an important holy site for Smartha Tradition. The name of the city it stands on, Thiruvananthapuram, in Malayalam and Tamil translates to "The City of Ananta" (Ananta being a form of Vishnu). The temple is built in an intricate fusion of the Kerala style and the Dravidian style of architecture, featuring high walls, and a 16th-century gopuram. While as per some traditions the Ananthapura Temple in Kumbla in Kerala's Kasaragod district is considered as the original spiritual seat of the deity ("Mulasthanam"), architecturally to some extent, the temple is a replica of the Adikesava Perumal Temple in Thiruvattar in Kanyakumari district of Tamil Nadu.

The principal deity is Padmanabhaswamy (Sanskrit: पद्मनाभस्वामि, IAST: Padmanābhasvāmi), a form of Vishnu enshrined in the "Anantashayana" posture, engaged in eternal yogic sleep on his serpent mount named Shesha. Padmanabhaswamy is the tutelary deity of the Travancore royal family. The titular Maharaja of Travancore, Moolam Thirunal Rama Varma, is the current trustee of the temple.

The Malik Dinar Mosque, also known locally as the Malik Deenar Masjid and Malik Deenar Juma Masjid, and officially known as the Hazrath Malik Deenar Grand Juma Masjid, is a Sufi Sunni mosque and dargah, located in Thalangara, in the town of Kasaragod, in the state of Kerala, India. Founded by Malik Dinar and believed to been completed in c. 22 AH (642/643 CE), it is one of the oldest mosques in India. The two-storey mosque was built in the Kerala-Islamic traditional style; and was extensively remodelled in the Islamic style in 2018.

In addition to the mosque and dargah, the complex includes a madrasa, cemetery, and orphanage.

The Vadakkumnathan Temple is an ancient Hindu temple dedicated to Shiva in Thrissur, in the Thrissur district of Kerala, India. The temple is a classical example of the architectural style of Kerala and has one monumental tower on each of the four sides in addition to a koothambalam. Mural paintings depicting various scenes from the Mahabharata can be seen inside the temple. The shrines and the Kuttambalam display vignettes carved in wood. The temple, along with the mural paintings, has been declared as a National Monument by India under the AMASR Act. According to popular local lore, this is the first temple built by Parashurama, the sixth avatar of Vishnu. Thekkinkadu Maidan, encircling the Vadakkumnathan Temple, is the main venue of the renowned Thrissur Pooram festival.

In 2012, the Archaeological Survey of India (ASI) has recommended 14 sites, including Vadakkumnathan Temple and palaces, from Kerala to include in the list of UNESCO World Heritage Sites. The temple is also the first one among the 108 Shiva Temples in ancient Kerala, established by Parashurama, and is mentioned in the Shiva Temple Stotra as Shrimad-Dakshina Kailasam, meaning 'Mt. Kailash of the South'.
