<p>A <b>lintel</b> or <b>lintol</b> is a type of <a href="Beam_(structure)" title="Beam (structure)">beam</a> (a horizontal structural element) that spans openings such as <a href="Portal_(architecture)" title="Portal (architecture)">portals</a>, <a href="Door" title="Door">doors</a>, <a href="Window" title="Window">windows</a> and <a href="Fireplace" title="Fireplace">fireplaces</a>. It can be a decorative architectural element, or a combined ornamented/structural item. In the case of windows, the bottom span is referred to as a <a href="Window_sill" title="Window sill">sill</a>, but, unlike a lintel, does not serve to bear a load to ensure the integrity of the wall.
Modern-day lintels may be made using <a href="Prestressed_concrete" title="Prestressed concrete">prestressed concrete</a> and are also referred to as beams in <a href="Beam_and_block" title="Beam and block">beam-and-block</a> slabs or as ribs in rib-and-block slabs. These prestressed concrete lintels and blocks can serve as components that are packed together and propped to form a <a href="https://en.wiktionary.org/wiki/Suspended" class="extiw external" title="wiktionary:Suspended">suspended</a>-floor <a href="Concrete_slab" title="Concrete slab">concrete slab</a>.

<meta property="mw:PageProp/toc">
<div class="mw-heading mw-heading2"><h2 id="Structural_uses">Structural uses</h2></div>
<p>In worldwide architecture of different eras and many cultures, a lintel has been an element of <a href="Post_and_lintel" title="Post and lintel">post and lintel</a> construction. Many different building materials have been used for lintels.<sup id="cite_ref-pittdef_3-0" class="reference"><a href="#cite_note-pittdef-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup>
</p><p>In <a href="Classical_architecture" title="Classical architecture">classical Western architecture</a> and construction methods, by <i><a href="Merriam-Webster" title="Merriam-Webster">Merriam-Webster</a></i> definition, a lintel is a load-bearing member and is placed over an entranceway.<sup id="cite_ref-pittdef_3-1" class="reference"><a href="#cite_note-pittdef-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> The lintel may be called an <a href="Architrave" title="Architrave">architrave</a>, but that term has alternative meanings that include more structure besides the lintel. The lintel is a structural element that is usually rested on stone pillars or stacked stone columns, over a portal or entranceway.
</p><p>A lintel may support the chimney above a fireplace, or span the distance of a path or road, forming a stone lintel bridge.
</p>
<div class="mw-heading mw-heading2"><h2 id="Ornamental_uses">Ornamental uses</h2></div>
<p>The use of the lintel form as a decorative building element over portals, with no structural function, has been employed in the architectural traditions and styles of most cultures over the centuries.
</p><p>Examples of the ornamental use of lintels are in the <a href="Hypostyle" title="Hypostyle">hypostyle</a> halls and <a href="Slab_stela" title="Slab stela">slab stelas</a> in <a href="Ancient_Egypt" title="Ancient Egypt">ancient Egypt</a> and the <a href="Indian_rock-cut_architecture" title="Indian rock-cut architecture">Indian rock-cut architecture</a> of <a href="List_of_Buddhist_temples" title="List of Buddhist temples">Buddhist temples</a> in caves. Preceding prehistoric and subsequent Indian Buddhist <a href="Temple" title="Temple">temples</a> were wooden buildings with structural load-bearing wood lintels across openings. The rock-cut excavated cave temples were more durable, and the non-load-bearing carved stone lintels allowed creative ornamental uses of classical Buddhist elements. Highly skilled artisans were able to simulate the look of wood, imitating the nuances of a wooden structure and the wood grain in excavating cave temples from monolithic rock.<sup id="cite_ref-keay_4-0" class="reference"><a href="#cite_note-keay-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup>
In freestanding Indian building examples, the <a href="Hoysala_architecture" title="Hoysala architecture">Hoysala architecture</a> tradition between the 11th and 14th centuries produced many elaborately carved non-structural stone lintels in the Southern <a href="Deccan_Plateau" title="Deccan Plateau">Deccan Plateau</a> region of southern India. The <a href="Hoysala_Empire" class="mw-redirect" title="Hoysala Empire">Hoysala Empire</a> era was an important period in the development of art and architecture in the South Indian <a href="Kannadiga" class="mw-redirect" title="Kannadiga">Kannadiga</a> culture. It is remembered today primarily for its <a href="Hindu_temple" title="Hindu temple">Hindu temples</a>' <i><a href="Mandapa" title="Mandapa">mandapa</a></i>, lintels, and other architectural elements, such as at the <a href="Chennakeshava_Temple%2C_Belur" title="Chennakeshava Temple, Belur">Chennakesava Temple</a>.
</p><p>The <a href="Maya_civilization" title="Maya civilization">Maya civilization</a> in <a href="The_Americas" class="mw-redirect" title="The Americas">the Americas</a> was known for its sophisticated art and monumental architecture. The Mayan city of <a href="Yaxchilan" title="Yaxchilan">Yaxchilan</a>, on the <a href="Usumacinta_River" title="Usumacinta River">Usumacinta River</a> in present-day southern Mexico, specialized in the stone carving of ornamental lintel elements within structural stone lintels.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> The earliest carved lintels were created in 723 CE. At the Yaxchilan archaeological site there are fifty-eight lintels with decorative pieces spanning the doorways of major structures. Among the finest Mayan carving to be excavated are three temple door lintels that feature narrative scenes of a queen celebrating the king's anointing by a god.<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup>
</p>
<div class="mw-heading mw-heading2"><h2 id="Radiation_protection">Radiation protection</h2></div>
<p>Lintels may also be used to reduce scattered radiation in medical applications. For example, <a href="Linear_particle_accelerator#Medical_linacs" title="Linear particle accelerator">Medical linacs</a> operating at high energies will produce activated neutrons which will be scattered outside the treatment bunker maze with a dose rate that depends on the maze cross section. Lintels may be visible or recessed in the roof of the facility, and reduce dose rate in publicly accessible areas by reducing the maze cross section.<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup>
