Thiruvalla temple is one of the major temples of Kerala and a fine sampling of its long-established style of temple architecture. The temple has many shrines though it is mainly dedicated to Lord Vishnu. The 50- feet high flag post is of stonework. An icon of garuda, vehicle of Lord Vishnu, is fixed atop the flag post. A exclusive attraction of this temple is the Kathakali performance staged every evening, as ritual offering. It is supposed that Vishnu, the principal deity, watches the performance from his abode. Ladies are allowed entry to the sanctum sanctorum only on two days; 'Vishu' and 'Thiruvathira'. Annual festival, 'Uthraseeveli' is famous on the 'Makayiram' asterism in 'Meenam' (March - April). Apart from the spiritual ceremonies, cultural programmes are also held.
