In 1831 Major Jonathan Forbes of the 78th Highlanders of the British army, while returning on horseback from a trip to Pollonnuruwa, came across the "bush covered summit of Sigiriya". Sigiriya came to the attention of antiquarians and, later, archaeologists. Archaeological work at Sigiriya began on a small scale in the 1890s. H.C.P. Bell was the first archaeologist to conduct extensive research on Sigiriya. The Cultural Triangle Project, launched by the Government of Sri Lanka, focused its attention on Sigiriya in 1982. Archaeological work began on the entire city for the first time under this project. There was a sculpted lion's head above the legs and paws flanking the entrance, but the head broke down many years ago.
Sigiriya consists of an ancient castle built by King Kasiappan during the 5th century. The Sigiriya site has the remains of an upper palace sited on the flat top of the rock, a mid-level terrace that includes the Lion Gate and the mirror wall with its frescoes, the lower palace that clings to the slopes below the rock, and the moats, walls, and gardens that extend for some hundreds of metres out from the base of the rock.
The site is both a palace and a fortress. Despite its age, the splendour of the palace still furnishes a stunning insight into the ingenuity and creativity of its builders. The upper palace on the top of the rock includes cisterns cut into the rock that still retain water. The moats and walls that surround the lower palace are still exquisitely beautiful

Site plan
Sigiriya is considered one of the most important urban planning sites of the first millennium, and the site plan is considered very elaborate and imaginative. The plan combined concepts of symmetry and asymmetry to intentionally interlock the man-made geometrical and natural forms of the surroundings. On the west side of the rock lies a park for the royals, laid out on a symmetrical plan; the park contains water-retaining structures, including sophisticated surface/subsurface hydraulic systems, some of which are working even today. The south contains a man-made reservoir; these were extensively used from the previous capital of the dry zone of Sri Lanka. Five gates were placed at entrances. The more elaborate western gate is thought to have been reserved for the royals

Sigiriya
Sigiriya (Lion Rock, Sinhalese - සීගිරිය, pronounced see-gee-REE-yah) is located in the central Matale District of the Central Province, Sri Lanka in an area dominated by a massive column of rock nearly 200 meters high. According to the ancient Sri Lankan chronicle the Culavamsa the site was selected by King Kasyapa (477 – 495 AD) for his new capital. He built his palace on the top of this rock and decorated its sides with colourful frescoes. On a small plateau about halfway up the side of this rock he built a gateway in the form of an enormous lion. The name of this place is derived from this structure —Sīhāgiri, the Lion Rock. The capital and the royal palace were abandoned after the king's death. It was used as a Buddhist monastery until the 14th century.

Akashi Kaikyō Bridge

Architecture(Akashi Kaikyō Bridge)

Main supporting towers
The bridge has three spans. The central span is 1,991 m (6,532 ft), and the two other sections are each 960 m (3,150 ft). The bridge is 3,911 m (12,831 ft) long overall. The two towers were originally 1,990 m (6,529 ft) apart, but the Great Hanshin earthquake on January 17, 1995, moved the towers so much (only the towers had been erected at the time) that the span had to be increased by 1 m (3.3 ft).
The bridge was designed with a two hinged stiffening girder system, allowing the structure to withstand winds of 286 kilometres per hour (178 mph), earthquakes measuring to 8.5 on the Richter scale, and harsh sea currents. The bridge also contains pendulums that are designed to operate at the resonance frequency of the bridge to dampen forces. The two main supporting towers rise 282.8 m (928 ft) above sea level, and the bridge can expand because of heat by up to 2 m (7 ft) over the course of a day. Each anchorage required 350,000 tonnes (340,000 long tons; 390,000 short tons) of concrete. The steel cables have 300,000 kilometres (190,000 mi) of wire: each cable is 112 centimetres (44 in) in diameter and contains 36,830 strands of wire.
The Akashi-Kaikyo bridge has a total of 1,737 illumination lights: 1,084 for the main cables, 116 for the main towers, 405 for the girders and 132 for the anchorages. On the main cables three high light discharged tubes are mounted in the colors red, green and blue. The RGB model and computer technology make for a variety of combinations. Currently, 28 patterns are used for occasions as national or regional holidays, memorial days or festivities

Akashi Kaikyō Bridge
History
Before the Akashi Kaikyō Bridge was built, ferries carried passengers across the Akashi Strait in Japan. This dangerous waterway often experiences severe storms and, in 1955, two ferries sank in the strait during a storm, killing 168 people. The ensuing shock and public outrage convinced the Japanese government to develop plans for a suspension bridge to cross the strait. The original plan called for a mixed railway-road bridge, but when construction on the bridge began in April 1988, the construction was restricted to road only, with six lanes. Actual construction did not begin until May 1988, and the bridge was opened for traffic on April 5, 1998.[3] The Akashi Strait is an international waterway that necessitated the provision of a 1,500-metre (4,921 ft)-wide shipping lane.
