Add 'place of activity' to basic module

Hello, at this website, www.franciscus-parochie.nl , I've added in the right column the basic module of JEM. In some way I managed to add the place of the event to the activity. Now I want to do the same in the restyled version, but I can't discover which file I have to change and in which way.
Can someone help me?

what do you mean with restyled version? if you mean the RESPONSIVE JEM, then you find this in:
[YOUR TEMPLATE]/html/mod_jem/default.php. This overwrites the default.php in the modules/mod_jem/tmpl/default.php. But the normla helper and css in the modules/mod_jem is used.
