Padova is not a FIR, it is a portion of airspace delegated from Milano (LIMM) ACC to Padova (LIPP) ACC. LIMM FIR includes both LIPP and LIMM ACCs. The sector LIMM_N_CTR, on 127.450, provides top-down coverage for both LIMM and LIPP ACCs if LIPP_N_CTR is not online. LIPP_N_CTR can be opened independently however when online it only covers LIPP ACC. Here you can see a detailed diagram of LIMM FIR.
Hope this helps
