Phare de la Panela, Maritime lighthouse in Montevideo Bay, Uruguay.

Phare de la Panela is a cylindrical lighthouse tower in the Río de la Plata facing Montevideo, Uruguay. It is painted with red and white stripes and stands 12 meters tall on a concrete base protected by granite blocks. The tower was originally metal and later rebuilt in fiberglass.

The lighthouse was built and lit in 1915 on the Río de la Plata opposite Montevideo. A storm soon after its inauguration destroyed much of the structure, leaving a 12-metre tower. On 10 February 2004 the Uruguayan postal service issued a stamp, code 2004-04-S, worth 54 pesos in its honour.

The lighthouse appears on a 54-peso Uruguayan stamp issued by the Correo Uruguayo on 10 February 2004, code 2004-04-S, which made the structure a postal subject. Its red and white stripes serve as a daytime landmark for sailors navigating the Río de la Plata opposite Montevideo.

The lighthouse stands offshore in the Río de la Plata, facing Montevideo, so it is seen from the water or the coast rather than entered; there is no tower staircase open to visitors. Its solar-powered light shows one flash every ten seconds, and an acoustic bell sounds on foggy days.

The tower lost much of its structure in a severe storm after 1915, leaving a 12-metre stump; the present fibreglass tower, painted in red and white stripes, replaced the original metal one. A fog bell and solar power now keep it running.
