Sastha Temple is a beautiful shrine situated near Govt Arts College at Thycaud in Thiruvananthapuram. This ancient temple enshrines Lord Ayyappa as the presiding deity. Devotees believe that one can accomplish all one's desires by worshipping Thycaud Sastha.
Sastha Temple, which has been maintained recently, is an excellent example of the Kerala style of architecture. Neeranjanam, which is done in order to remove the 'Shani dosham', or the evil influence of the planet Shani, is the main offering at the temple. Mandala Puja and Makar Sankranti are the major festivals celebrated at the temple.
