250px-Faro_Punta_TunaLight­house paint­ed white, lantern black; the keeper’s house is paint­ed cream with white trim. The orig­i­nal 3rd order Fres­nel lens, some­what dam­aged by van­dals, remains in the tow­er but is not in use.   In 2006, George Van Parys found­ed a sup­port orga­ni­za­tion called Faro de Pun­ta Tuna or Pun­ta Tuna Light­house to work toward own­er­ship and restora­tion of the light­house. In 2009 the light­house became avail­able for trans­fer under NHLPA. Locat­ed south­east of Maun­abo on a sharp promon­to­ry at the south­east­ern most point of the island.

The Maun­abo or Pun­ta Tuna light­house entered ser­vice on Novem­ber 18, 1892. It was designed by Joaquín Gis­bert and con­struct­ed by Adrián Duf­faut over the promon­to­ry known as Pun­ta Tuna or Pun­ta de la Tuna, at the south­east­ern tip of the island. The build­ing mea­sures 91 feet long by 41 feet wide and was orig­i­nal­ly paint­ed white with dark-gray details. Its twin was the first Aguadil­la light­house, from which it only dif­fered by its col­or and by the shape of the tower’s cor­nice. The tow­er is octag­o­nal, 43-feet tall, and placed at the cen­ter of the build­ing.

The lamp fuel stor­age room was locat­ed behind the tow­er and ven­ti­lat­ed to the out­side through a small blind. A sub­stan­tial ren­o­va­tion took place around 1960 which includ­ed the redis­tri­b­u­tion of inter­nal spaces, the con­struc­tion of a vestibule for the entrance, the addi­tion of a rear door, and the sub­sti­tu­tion of the brick roof by a con­crete one. The third-order lens, which pro­ject­ed its light eigh­teen miles away, was used until the late 1970s. This lens and that of the San Juan light­house are the only orig­i­nal lens­es remain­ing in our light­hous­es; unfor­tu­nate­ly, two of the three pan­els of the Maun­abo lens were dam­aged by van­dals. The clock mech­a­nism that rotat­ed the lens was sub­sti­tut­ed in 1939 by an elec­tric motor but remains in the lantern, and the weights that turned it are in the stairway’s cen­tral col­umn. Cur­rent­ly the light is pro­duced by a small bea­con pow­ered by solar pan­els. The tower’s iron balustrade, although oxi­dized, retains its orig­i­nal beau­ty. The light­house is admin­is­tered by the Maun­abo munic­i­pal­i­ty since 2006 and opens to the pub­lic.
