Did you mean “Mukh/Mukharvind” (the holy face/mouth of a deity) and want a related Jain pilgrimage city? Two very well‑known places are:

• Mahudi, Gujarat – famous for the Mukharvind darshan of Shri Ghantakarna Mahavir.
• Nakoda (near Balotra), Rajasthan – renowned for Nakoda Bhairavji’s Mukharvind; the main temple is of Shri Parshvanath.

If by “Mukh” you meant a tirth name that sounds similar, many people also refer to Muktagiri Tirth (Madhya Pradesh), though its name is “Mukta,” not “Mukh.”
