La Pyramide Inversée (The Inverted Pyramid) is a skylight constructed in the Carrousel du Louvre shopping mall in front of the Louvre Museum in France.
 It may be thought of as a smaller sibling of the more famous Louvre Pyramid proper, yet turned upside down: its upturned base is easily seen from outside.
The Muttart Conservatory is a botanical garden located in the North Saskatchewan river valley, across from the downtown core in Edmonton, Alberta, Canada.
 One of the best-known landmarks of Edmonton, the conservatory consists of three city-operated greenhouses, public gardens, as well as four feature pyramids for display of plant species found across three biomes, with the fourth pyramid hosting as a seasonal display.
 A fifth minor skylight pyramid lights up the central foyer.
Abu Rawash (also spelled "Abu Roach", Abu Roash; Arabic: ابو رواش‎ ‎   ] ), 8 km to the North of Giza, is the site of Egypt's most northerly pyramid, also known as the lost pyramid — the mostly ruined Pyramid of Djedefre, the son and successor of Khufu.
 Originally, it was thought that this pyramid had never been completed, but the current archaeological consensus is that not only was it completed, but that it was built about the same size as the Pyramid of Menkaure – the third largest of the Giza pyramids.
 One notable fact about the pyramid at Abu Roash is that the upper most part of the pyramid has seemingly disappeared, revealing the internal passage that runs down into the bedrock.
 Explanations to why this pyramid is missing its top vary.
 The second point of interest that this pyramid provides is that it is built on top of a hillock.
 The builders faced the colossal task of not only hauling megalithic stones up a pyramid but also up a hillock.
Suzuki F10D engine is an inline 4-cylinder 1061cc engine that was developed in India by Maruti Suzuki for the domestic market.
 It was debuted in the Maruti Wagon-R in India in 2001.
 It was briefly installed in Maruti Alto and it was the engine that the first Maruti Zen Estilo came with.
 This engine is very similar to the 3-cylinder F8D 12-valve engine that was optional on the Maruti 800 at the time.
 The bore and stroke of F10D is the same as that of the smaller sibling and shares quite a few parts like pistons, rings, conrods and valves.
 The cast-iron engine block is very similar to that of the older F10A 970cc engine that powered the earlier Maruti Gypsy and Maruti 1000.
 Both F10A and F10D shares the same stroke length; but interchangeability of parts between these two engines is not known.
The Honda RVF400R (NC35) was a sport bike manuafactured by Honda from 1994 to 1996.
 It was powered by a 16 valve double overhead geardriven cam 400 cc 90° V4 four-stroke engine, and was known for its fantastic handling capabilities.
 Two models were produced, the T (1994) and the R (1996), although they differed only in their paint schemes.
 The RVF (as it was marketed by Honda in Japan) finished production in 1996, though unsold RVFs remained available to purchase from Japanese Honda dealers through to 2001.
 The RVF400R is the smaller sibling of RVF750R (RC45), as the VFR400R (NC30) was to the VFR750R (RC30).
The Louvre Pyramid ("Pyramide du Louvre") is a large glass and metal pyramid designed by Chinese-American architect I.M. Pei, surrounded by three smaller pyramids, in the main courtyard ("Cour Napoléon") of the Louvre Palace ("Palais du Louvre") in Paris.
 The large pyramid serves as the main entrance to the Louvre Museum.
 Completed in 1989, it has become a landmark of the city of Paris.
Cemetery GIS is a necropolis in the Giza Plateau.
 It derives its name from its proximity to pyramid G I (Khufu).
 The tombs are located on the south side of that pyramid and hence the name G I South Cemetery.
 Reisner thought the cemetery a continuation of the G7000 cemetery which is part of the Giza East Field.
 The construction postdates that of mastaba G 7070 of Sneferukhaf.
 Junker dated the cemetery to the reign of Menkaure based on the presence of granite powder thought to derive from the dressing of the second pyramid at Giza.
 Reisner allows for a possible construction date dating to the reign of Khafre.
Louis Béroud (January 17, 1852, Lyon-October 9, 1930, Paris) was a French painter of the late 19th, early 20th century.
 Some of his paintings are visible at the Musée Carnavalet and The Louvre in Paris.
 On August 22, 1911, Béroud came to The Louvre to sketch his painting "" but where the famous "La Joconde", by Leonardo da Vinci, should have stood, he found four iron pegs.
 Béroud contacted the section head of the guards, who thought the painting was being photographed for marketing purposes.
 A few hours later, Béroud checked back with the section head of the museum, and it was confirmed that the "Mona Lisa" was not with the photographers.
 The Louvre was closed for an entire week to aid in investigation of the theft.
The Pyramid of Djedefre consists today mostly of ruins located at Abu Rawash in Egypt.
 It is Egypt's most northerly pyramid, and is believed to have been built by Djedefre, son and successor to king Khufu.
 Though some Egyptologists in the last few decades have suggested otherwise, recent excavations at Abu Rawash carried out by Dr. Michael Baud of the Louvre Museum in Paris suggest the pyramid was in fact never finished.
 If completed, however, it is suggested to have been about the same size as the Pyramid of Menkaure — the third largest of the Giza pyramids.
 It is believed to have originally been the most beautiful of the pyramids, with an exterior of polished, imported granite, limestone and crowned with a large pyramidion.
 It is also believed for this reason the completed pyramid was largely deconstructed by the Roman Empire to build their own construction projects after the conquest of Egypt under Roman Emperor Augustus.
 The pyramid's ancient name was "Djedefre's Starry Sky".
The Carrousel du Louvre is an underground shopping mall in Paris, France.
 The name refers to two nearby sites, the Louvre museum and the Place du Carrousel.
 The mall contains a famous skylight, "La Pyramide Inversée" (the "Inverted Pyramid"), which plays an important role in the best-selling book "The Da Vinci Code".
