Solved Public view of Google Calendar

I need to make the Priory's church and halls Google calendar available to all via my village web site. That is straight forward. However when I test it I find that at the bottom left of the calendar there is a link "Add to Google calendar" which appears to give more access than I want give.
I am happy to give anyone who needs more information to advise me the address of the web site but I am not putting it here as it would effectively identify me.

Found answer - sorry to trouble anyone that looked!
It is a link that allows the viewer to add the calendar to their own list of calendars. Add to personal Google Calendar might have been clearer!
