The Barclay de Tolly Mausoleum commemorates one of the most famous Russian commanders who fought Napoleon in 1812 and 1813 and who culminated his triumph with a march through Paris in March 1814. His family was partially of Scottish extraction but from the 17th century had lived in what is now Latvia and Lithuania. Following the Russian conquest of Finland in 1809, he was the first governor-general there until 1812.
Jõgeveste was the estate of his wife's family and his body was brought back there after his death in East Prussia in 1818. The mausoleum was completed in 1823 on the instructions of de Tolly's wife Eleanor von Smitten. She commissioned Apollon Shchedrin, a leading St Petersburg architect, to design it and its structure has remained intact since then, although the two coffins were opened during World War II. The exterior design suggests parallels to a Roman triumphal arch, the interior to a chapel with an altar recess where the bust of de Tolly is placed. The statue on the right is of Athena, the Greek goddess of war, and on the left the statue of a sitting woman represents the symbol of mourning. Outside are the tombs of de Tolly's son and daughter-in-law and a Soviet memorial to soldiers killed in the 1944 invasion of Estonia.
The trulli, typical limestone dwellings of Alberobello in the southern Italian region of Puglia, are remarkable examples of corbelled dry-stone construction, a prehistoric building technique still in use in this region. These structures, dating from as early as the mid-14th century, characteristically feature pyramidal, domed, or conical roofs built up of corbelled limestone slabs. Although rural trulli can be found all along the Itria Valley, their highest concentration and best preserved examples of this architectural form are in the town of Alberobello, where there are over 1500 structures in the quarters of Rione Monti and Aja Piccola.
The property comprises six land parcels extending over an area of 11 hectares. The land parcels comprise two districts of the city (quarters or Rione Monti with 1,030 trulli; Rione Aia Piccola with 590 trulli) and four specific locations.
Trulli (singular, trullo) are traditional dry stone huts with a corbelled roof.
