:::::I would never have thought of having a Geobox for bells, but why not, the Geobox 2.0 template can accomodate real any object connected with geography without the need to set up a specialized template. The blank template is here: Template:Geobox/type/bell and that's all that's needed. It's just the Template:Geobox/type/all blank template stripped of fields which probably won't be needed for bells (but the template can still make use of them if needed, e.g. if an old bell is inhabited by some rare bat species the field animal can be added … joking about the bats, of course -) As you can see, some fields are adjusted/"retyped". The default unit for length is km/mi (the Geoboxes will mostly be used for larger objects), the width field is "retyped" to diameter, the established dates are renamed too, if need you can add more, e.g. established3 and established3_type = recast etc. I would have forgotten, a test page is here: Illinois Freedom Bell.

I've put it in the same group as buildings which have pale yellow color. This is, however, not the final one. The Geoboxes haven't been used so far buildings and other man made objects so I only suggested this color. It could be anything but different from the other group colors in the series (see Template:Geobox/type/all). –  (talk)
