Batan is one of oldest town founded in the province Aklan. Batan was formerly an encomienda of Miguel Rodriguez in 1591. The parish in Batan was established by the Augustinians in 1601 under the patronage of Our Lady of Immaculate Conception. Batan was first incorporated to Aclan or Aklan (now Kalibo) in 1603 and in 1789 it became an independent municipality. In 1903, Batan was again incorporated to the new town of New Washington and became independent again in 1931. 
In 1957, the Kalantiaw National Shrine marker was erected by the Philippine Historical and Cultural Society to honor the significance of Datu Kalantiaw where it displays a copy of the “original manuscript” of the Code. It was built in this former school building near the port which houses the province's historical mementos and antiques, including the original manuscript of the code which the Spaniards obtained from an old chief and translated. In 2004 however, after years of investigation and historical findings, the National Historical Institute concluded that the Code of Kalantiaw was fake and a hoax. Remnants of the Kalantiaw National Shrine marker still remain in Batan.
