I am not sure about Kollur and Mayapur; but regarding Swamithope,
"Take a look into the citations 4,5,6,7 of this article. The Car festival here attracts crowd from two states. Another festival in Swamithope (Ayya Vaikunda Avataram) was celebrated with a holiday for three districts. Is there any other Temple festival which is celebrated with holiday(other than local holiday)? - 184.108.40.206 (talk) 21:19, 4 July 2008 (UTC)"
The above is taken from Template talk:Famous Vishnu temples. I feel it must be added. - White Dot...!!!® 14:57, 7 September 2008 (UTC)
But it of the Ayyavazhi religion, not of mainstream Hinduism, so need not be mentioned here.--Redtigerxyz (talk) 05:05, 8 September 2008 (UTC)
There may be views that Ayyavazhi is a religion. But see the intro of Ayyavazhi article. There are creadible sources that Ayyavazhi is viewed a Hindu sect and so, I feel, swamithope must be added amongst that of Hindu. - White Dot...!!!® 16:58, 9 September 2008 (UTC)
Every other city or town or village in India has a "famous" holy shrine, or thus is a holy city. Thus every such city can not be named here. Only major ones should be included here.--Redtigerxyz (talk) 04:06, 10 September 2008 (UTC)
The link goes to a disambiguation page, and none of the articles linked from there appear relevant to the topic of the template. What Wikipedia article describes this Hindu holy city? --R'n'B (call me Russ) 14:11, 15 July 2009 (UTC)
Never mind, it looks like it was an erroneous edit. --R'n'B (call me Russ) 14:16, 15 July 2009 (UTC)
