The only helipad I know in San Marino is the one at San Marino Filed

Borgo Maggiore has an international heliport, but I have not been able to find an identifier or location for it. Right now, this airport is pointing to the main traffic circle in the centre of Borgo Maggiore, which almost certainly is *not* a heliport.
Please help if you know or can find the location.
