"Sacred" implies the involvement of a deity. Buddhism has no deity. Therefore no object is sacred in Buddhism.
Buddhism has symbols like the eight spoked wheel, but these are neither real objects or sacred.
Buddhism has relics but these are souvenirs and aides memoires for Buddhists to help them focus in meditation.
Sacred is usually meant to mean "important to, or related to a deity". Buddhism has no deity so nothing is sacred. Objects, sites, books, relics can be held in high esteem or revered as an aide-mémoire to Buddhists in remembering or feeling connected to significant events or people.
There are symbols which Buddhists use as aides memoires for their meditation, symbols which represent aspects of Budhist teaching as culture but none of these is "sacred". Sacred implies that the object is directly tied to the deity worshipped by the adherents. Buddhism has no deity, and hence, no sacred anything. Consider the Christian cross which is generally venerated as a sacred symbol. Christians get quite upset if you denigrate this symbol. Buddhists would not have the same reaction to interacting with any eight spoked wheel.
well sacred objets are objects that a religion use and treat in a special way to get closer to their god or gods.
Hindu sacred objects, are something that Hindu's believe in, and have traditional value, like prayer beads or a Tilaka.
Ultimately the direct experience of mind although on the relative level; texts , pictures, relics and prayers are just some of the things that may all be held in reverence.

A stupa is a symbol of enlightenment and is one of the most ancient icons of Buddhist art. Stupas are also the oldest and most prevalent forms of Buddhist architecture. More than just being examples of art and architecture, these holy monuments were designed with deep symbolism and sacred geometry. Filled with Buddhist relics, and other holy objects, stupas emanate blessings and peace. A stupa is the most sacred monument found in all of the ancient Buddhist countries. Unique amongst all forms of sacred architecture, it is the quintessential symbol of enlightenment. Stupas are filled with sacred images, mantras and the relics of holy beings. The foundation, symmetry, orientation and contents of the stupa create incredible power to those who even look upon it. It has the potential to transcend the limitations of language to activate enlightened knowledge. "A stupa is a place where all the Buddhas are abiding. Those beings who don't have the karma actually to see Buddha need the holy objects of body, speech and mind - statues, scriptures, stupas - as a field for accumulating merit." - Guhyasamaja Root Text
