The historic complex is composed of the following monuments: In 1410, Voivode Alexander the Good (Alexandru cel Bun) granted a fief to boyar and member of Sfatul Domnesc ("Prince's Council"), Miclăuș, an estate located near the Siret River plains.

On April 25, 1591, the nobleman's descendants sold the estate to treasurer Simon Stroici (1550–1623), who built a mansion on the property and fortified the village of Miclăușeni in 1598.

Feudal peasants and gypsies worked the land, whose descendants to this day have surnames describing their feudal professions; Bucătaru(Chef), Muraru (Mill worker), Pitaru (Baker), Curelaru (leather cutter), Mindirigiu (mattress maker), Bivolaru (livestock hearder), Surugiu (coachman), as described in the book "Castelul Miclăușeni în cultura română" (Miclăușeni Castle and Romanian Culture), Ed.

The son of Dimitrie, Alecu Sturdza Miclăușanu, built a park of 42 hectares (100 acres) all stylized as an English Garden with ornamental tree species and numerous flower beds.

The Palace was used as a home for orphans under Communist rule, counter to the wishes of daughter Catherine Sturdza who became a nun and donated the property to become a nunnery, which it finally became in 1990.

1170 of 2 October 2003 it was established, among other things, to carry out emergency repairs to the Sturdza Palace (Miclăușeni village, Iași County) and landscaping works in the adjacent areas.

In 2004, having obtained a World Bank grant of approximately 2.4 million lei (685,700 euro), the Metropolitanate of Moldavia and Bukovina began the restoration of the palace and its outbuildings.

The exterior walls of the building have been adorned with numerous ornamentations in high relief, including blazonries inspired by the Sturdza family coat of arms: a lion with a sword and an olive branch, or symbolic elements, made in 1898 in Art Nouveau style by the architect Iulius Reinecke.

The neo-Gothic influences can be seen in decorations such as Gothic turrets, medieval armor, a manège hall, Latin dictons inscribed on the walls, an entrance tower with a bridge over the moat.

The wooden components of the building (doors, windows, wainscoting, interior staircases) are made of oak, lime and resinous wood, and are richly carved, profiled, fretworked and polished with shellac to furniture-style.
