What was the original direction of the Qibla for Muslims before it was changed towards the Kaaba in Mecca?

Explanation

For approximately 16 to 17 months after the migration to Madinah, Muslims prayed facing Masjid al-Aqsa (Bait-ul-Muqaddas) in Jerusalem. In 2 AH, while Prophet Muhammad (PBUH) was leading the Zuhr or Asr prayer at Masjid al-Qiblatayn (Mosque of the Two Qiblas), divine revelation (Surah Al-Baqarah, 2:144) commanded the Qibla shift toward the Kaaba in Mecca.
