Question: The tomb of Ferdowsi example of Achaemenid architecture, a style from which culture?
Context: Bahu Begum ka Maqbara is the Tomb of Queen Bride Begum Unmatuzzohra Bano alias Bahu Begum a memorial built for queen of Nawab Shuja-ud-Daula.  Its one of the tallest buildings in Faizabad and is a beautiful example of non-mughal Muslim architecture.  The Mausoleum of Bahu Begum created by Nawab Suja-ud-Daula in the memory of his loving wife is famous for the creative architectural brilliance with which it was designed and constructed.  Shuja-ud-daula's wife was the well known as Bahu Begum, who married the Nawab in 1743 and continued to reside in Faizabad, her residence being the Moti-Mahal.  Close by at Jawaharbagh lies her Maqbara, where she was buried after her death in 1816.  It is considered to be one of the finest buildings of its kind in Avadh, which was built at the cost of three lakh rupees by her chief advisor Darab Ali Khan.  A fine view of the city is obtainable from top of the begum's tomb.  Bahu Begum was a woman of great distinction and rank, bearing dignity.  Most of the Muslim buildings of Faizabad are attributed to her.  From the date of Bahu Begum's death in 1815 till the annexation of Avadh, the city of Faizabad gradually fell into decay.  The glory of Faizabad finally eclipsed with the shifting of capital from Faizabad to Lucknow by Nawab Asaf-ud-Daula. The Tomb of the Dancers or Tomb of the Dancing Women (Italian: "Tomba delle Danzatrici" ) is a Peucetian tomb in Ruvo di Puglia, Italy.  It was discovered in the Corso Cotugno necropolis in November 1833.  The date of its construction is uncertain, dates ranging from the end of the fifth century BC to the mid-fourth century BC have been proposed.  In any case, the tomb's frescoes are the oldest example of figurative painting in Apulia, together with another tomb in Gravina di Puglia.  The Peucetians borrowed the practice of painting tombs from the Etruscans, who had an important influence on their culture.  The tomb is named after the dancing women which appear on the frescoes in the tomb.  The panels with the frescoes are now exhibited in the Naples National Archaeological Museum, inv.  9353. Tomb of Ferdowsi (Persian: آرامگاه فردوسی‎ ‎ ) is a tomb complex composed of a white marble base, and a decorative edifice erected in honor of the Persian poet Ferdowsi located in Tus, Iran, in Razavi Khorasan province.  It was built in the early 1930s, under the Reza Shah, and uses mainly elements of Achaemenid architecture to demonstrate Iran's rich culture and history.  The construction of the mausoleum as well as its aesthetic design is a reflection of the cultural, and geo-political status of Iran at the time. The tomb of Marcus Vergilius Eurysaces the baker is one of the largest and best-preserved freedman funerary monuments in Rome.  Its sculpted frieze is a classic example of the "plebeian style" in Roman sculpture.  Eurysaces built the tomb for himself and perhaps also his wife Atistia around the end of the Republic (ca. 50-20 BC).  Located in a prominent position just outside today's Porta Maggiore, the tomb was transformed by its incorporation in the Aurelian Wall; a tower subsequently erected by Honorius covered the tomb, the remains of which were exposed upon its removal by Gregory XVI in 1838.  What is particularly significant about this extravagant tomb is that it was built by a freedman, a former slave. Persepolis (Persian: پرسپولیس) was the ceremonial capital of the Achaemenid Empire (ca. 550–330 BC ).  It is situated 60 km northeast of the city of Shiraz in Fars Province, Iran.  The earliest remains of Persepolis date back to 515 BC.  It exemplifies the Achaemenid style of architecture.  UNESCO declared the ruins of Persepolis a World Heritage Site in 1979. Akbari Architecture refers to the style of Indo-Islamic architecture conceived during the reign of Mughal Emperor Akbar.  His successors further added to this style, leading to the unique and individualistic 'Mughal' Style as we know it today.  Some shining examples of this style are Humayun's Tomb, which was the first of a long succession of garden-tombs (and a predecessor of the Taj Mahal), the Agra Fort, the abandoned city of Fatehpur Sikri and Akbar's own tomb. Tudor Revival architecture (commonly called mock Tudor in the UK) first manifested itself in domestic architecture beginning in the United Kingdom in the mid to late 19th century based on a revival of aspects of Tudor architecture or, more often, the style of English vernacular architecture of the Middle Ages that survived into the Tudor period.  It later became an influence in some other countries, especially the British colonies.  For example, in New Zealand, the architect Francis Petre adapted the style for the local climate.  Elsewhere in Singapore, then a British colony, architects such as R. A. J. Bidwell pioneered what became known as the Black and White House.  The earliest examples of the style originate with the works of such eminent architects as Norman Shaw and George Devey, in what at the time was thought of as a neo-Tudor design. Scholars Pavilion or Scholars Chartagi is a monument donated by the Islamic Republic of Iran to the United Nations Office at Vienna.  This monument architecture is a combination of Islamic architecture and Achaemenid architecture.  Statues of four famous Iranian scientists, Omar Khayyam, Al-Biruni, Muhammad ibn Zakariya al-Razi and Avicenna, are inside the pavilion.  This monument donated in June 2009 in occasion of Iran's peaceful developments in science. The "Parsian style" (New Persian:شیوه معماری پارسی) is a style of architecture (""sabk"") when categorizing the history of Persian/Iranian architectural development.  Although the Median and Achaemenid architecture fall under this classification, the pre-Achaemenid architecture is also studied as a sub-class of this category. Achaemenid architecture (Persian: معماری هخامنشیان) includes all architectural achievements of the Achaemenid Persians manifesting in construction of spectacular cities used for governance and inhabitation (Persepolis, Susa, Ecbatana), temples made for worship and social gatherings (such as Zoroastrian temples), and mausoleums erected in honor of fallen kings (such as the burial tomb of Cyrus the Great).  The quintessential feature of Persian architecture was its eclectic nature with elements of Assyrian, Egyptian, Median and Asiatic Greek all incorporated, yet producing a unique Persian identity seen in the finished product.  Achaemenid architecture is academically classified under Parsian architecture in terms of its style and design.
