Bar y Almacén del Hacha, Colonial bar in Ciudad Vieja, Uruguay.

Bar y Almacén del Hacha is a colonial building at the intersection of Buenos Aires and Maciel streets in Ciudad Vieja, known for its thick walls measuring about 60 centimeters. The structure preserves its original grating system, typical of storage houses from that period.

Registered in the Dirección de Catastro as a pulpería on 27 January 1817, when the department of Montevideo was created, the corner shop belonged to Juan Vázquez and was known as "La esquina de Vázquez". It later became a drinks depot and general store, and by the early 20th century an almacén, café and bar. The name comes from the 15 April 1794 murder of Bernardo Paniagua, the pulpería employee, killed with an axe blow by Domingo Gambini during a robbery attempt; Gambini was tried in Buenos Aires and hanged in Montevideo.

The bar's name comes from the axe blow that killed pulpería employee Bernardo Paniagua during a robbery attempt on 15 April 1794; the spot became known as the "esquina del hacha". Neighbours formed a friends' society that meets in summer at Pajas Blancas, and murga groups such as Asaltantes con Patente rehearsed at the door.

The bar sits at the corner of Buenos Aires and Maciel in the Guruyú area of Ciudad Vieja, near the Sarandí breakwater and the port. Its stone walls are 60 cm thick, the entrance keeps the original pulpería grille, and the patio holds a stone cistern. The upper floor rests on palm-trunk beams; the gas lighting pipes of the late 19th century were removed.

In 2004 the Uruguayan postal service issued 15,000 stamps of $16 each commemorating the anniversary of the Almacén del Hacha. The bar also appears in the Dirección Nacional de Cultura's Boliches en agosto programme and on the official Día del Patrimonio route.
