There are over a hundred major temple sites to be visited in and around Siem Reap-the remains in brick and stone of cities that were built by a succession of Khmer Kings between the 9th and 13th centuries.

All other civic and domestic buildings were built in timber and so have long since disappeared. Not much is known therefore about the lives of the civilians, although the remnants of the vast irrigation system that sustained the population and some 1,200 inscriptions found throughout the country indicate the size and complexity of the civilization.

Brick was mainly used for the earlier temples, with increasing use then being made of laterite, a rust colored mud stone, and finally of sandstone, which was mostly quarried from the Kulen hills, 40 kilometers to the north-east of Siem Reap. Many were built as temple mountains or pyramids, symbolic of the cosmic Mount Meru of Hindu mythology. The five tiered mountain at the center of the universe (the temple), was said to be encircled by seven chains of mountains (the enclosure walls) which were surrounded in turn by the sea (the moat).

It's unlikely that any future civilisation will ever be able to match the magnificence and mysticism of this extraordinary fairytale place. For the Alhambra is a unique creation spawned from the gold coffers of Moorish sultans, the creative minds of poets and philosophers and the agony of slave labour. Wars, sieges and years of neglect have failed to detract from the allure of the Alhambra which draws millions of visitors a year to a hilltop overlooking the city of Granada.

Visit the Alhambra today and you'll still find a mesmerising mixture of the most intricate tilework, filigree decoration and mosaics within its royal rooms and shaded courtyards. A sensual blend of bubbling fountains, dark green pools, white marble floors and enchanting passage ways draw you back through the centuries to a time and place where sultans once ruled and relaxed on silken cushions while naked beauties danced for them (accompanied by blind musicians!)

Jewels in the crown of the Alhambra include the legendary Court of the Lions with its famous fountain, the Hall of the Kings and Hall of the Queens, the royal baths and the magnificent Hall of the Two Sisters lavishly decorated with gold and lapis lazuli.

Within the grounds lies the most popular Parador hotel in Spain, housed within a 15 th century covent which was part of the Moorish palace before it was captured by the Christians in 1492. The hotel houses the former chapel where the crusading Catholic monarchs Isabella and Ferdinand were temporarily buried before being moved to their final resting place in Granada's Capilla Real. Be warned that if you want to stay in this particular Parador you'll probably have to book months in advance.

In July and August the Alhambra Palace is the main venue for the annual International Festival of Music and Dance which attracts some of the world's top orchestras, flamenco performers and ballet companies.

If you plan to visit in high season it's worth securing an entrance ticket in advance because this is one of Spain's top tourist attractions and numbers are restricted.

A tour of the Alhambra

Walking through the wood you come to the Puerta de la Justicia, built by Yusus I in 1348. Above the gate's first horseshoe arch there is a carved hand to symbolize defence against evil. The second horseshoe arch is decorated with many Arab inscriptions. There are beautiful blue and green azulejos.

After four right-angled bends (for reasons of defence), you come to the entrance to the Alhambra Palace itself. Nearby the Renaissance fountain (1545) dates from the time of Charles V and is the work of Pedro Machuca. The 14th century Puerta del Vino leads to the Plaza de los Aljibes (square of wells).

The 'Gate of Wine' displays the Nasrites´ artistic style to great advantage. To the west of the square there are the former buildings of the Alcazaba; to the east there is the Palace of Charles V and to the north the Palacio Arabe (the Alhambra Palace).

The Alcazaba is enclosed by ramparts; several of its towers survive. The Torre de la Vela is the most significant one, dominating a magnificent panorama of the city and surrounding areas.

Also of interest are the Torre del Homenaje (Keep), Torre Quebrada and Torre del Adarguero. Puerta de la Tahona, in the tower of the same name, affords access to the royal palaces.

The Mexuar palace was originally given over to administrative and judicial affairs; and the Royal Council used to meet here. Although now in a deficient state of repair, the main section is a hall centred around four columns and a modern fountain; this was used as a chapel from the 18th century until the 20th.

The north facade serves as a portico for the Cuarto Dorado ('Golden Room').

The facade on the other side of the Mexuar is called the Serrallo front, its artistic eaves are remarkable.

After the Serrallo facade, the visitor will reach the Patio de los Arrayanes ('Court of Myrtles'), also known as Patio de la Alberca, del Estanque or de los Mirtos, with a magnificent pool in the centre. Its arches are semicircular, with a voussoired structure. Special mention should be made of the wooden ceiling in the north gallery and the alabaster lamp-stands, with ceramics at the back, located in the jambs of the doorway.

Salon de Embajadores ('Ambassadors´ Hall'), also known as de Comares, is next, this was the centre of political and diplomatic life. Although it was once superbly decorated, it now retains only its artistic architectural design.

Continuing towrads the baths, the visitor will reach the Patio de la Reja ('Court of the Ruling') with its fountain and cypress trees.

Next to it is the Jardin de Lindaja ('Lindaraxa's Garden'), which does not correspond to the moorish period, but dates from the 16th century. It was designed to embellish the courtyard onto which Charles V's room gave. A post-Reconquest fountain, with an Arab basin, stands in the centre.

The Banos Reales ('Royal Baths') are next to Lindaraxa´s Garden. They display polychromatic decoration, predominately blue, green, gold and red in the main room, where there is also a small 16th century fountain. The Royal Baths comprise three further sections.

The Tocador de la Reina ('Queen´s Boudoir') is between the Ambassadors´Hall and the Harem. This room was built for the Empress Isabella and displays outstanding fresco paintings on the walls. By the door to one of the Emperor´s rooms there is a tablet recalling that Washington Irving, the author of The Alhambra, stayed there.

The artistically decorated Sala de los Ajimeces ('Hall of Mullioned Windows') id the first of the rooms making up the Harem, its ceiling was restored in the 16th century. The Sala de las Dos Hermanas ('Hall of the Two Sisters') is beyond 'Lindaraxa´s Balcony', Boabdil´s mother lived here after being repudiated by Muley Hacen. The decoration is superb, and the dome, of harmonious proportions.

The Sala de los Reyes, also called de la Justicia ('Hall of Kings/Justice'), lies to the east of the Court of Lions. It was a Christian church from the time that the royal mosque disappeared until the construction of the church of Santa Maria de la Alhambra, and is adorned by a painting of ten Moorish kings assembled in a meeting.

The Sala de los Abencerrajes ('Hall of the Abencerrages') is another important room, it seems that all the children of Muley Abul Hassan were executed here when he married Zoraida. The last room in the Harem is the

Sala de los Mocarabes (mocarabe - carpenter´s design of interlaced prisms), which now display baroque decoration on the ceiling.

This breathtaking landscape of the al-Hasa Oasis

Al-Hasa Oasis is the largest natural oasis in Saudi Arabia. It is located approximately 65 kilometers west of the Arabian Gulf and is home to just under one million people.

In ancient times, it was a key stopping point on trade routes between eastern Saudi Arabia, India, Persia and the Far East. Today, it is a collection of numerous small towns and villages all bound together by their dependence on the oasis.

The oasis extends over approximately 12,000 hectares (30,000 acres) and is irrigated by a flow of 60 or more artesian springs. A large underground aquifer provides water for approximately 3 million date palms as well as other agricultural crops.

Date farming has long been one of the main agricultural activities in the area, and today, local industries supply dates and date products throughout the Gulf region. Al-Hasa dates are considered some of the finest to be found throughout Saudi Arabia.

By the early 1960s, residents knew that the bounty of the oasis was in danger, both from the encroaching sand and from an outdated irrigation system. An ambitious irrigation project consisting of canals and above-ground viaducts was undertaken in 1962 by the government to supply water for farming in the area.

One of the interesting features of this irrigation system was the reservoirs that were constructed to supply water for domestic use as well as to provide swimming holes for local residents.

In 1965 a complementary project of reforestation and sand dune control also was undertaken with cooperation from agricultural experts working for Saudi Aramco. The encroaching sand had clogged many of the natural irrigation channels and was threatening to engulf several of the villages in the al-Hasa area. This project has been largely successful and may be visited today.

Now the oasis faces another threat - the aquifer is drying up as evidenced by archival photos showing higher water levels in the reservoirs in decades past. Palm trees still provide shade and nourishment in al-Hasa - as they have for centuries past and hopefully will for years to come.
