Kind Of Arch That Resembles A Hershey's Kiss

Introduction

When youthink of a Hershey’s Kiss, the first image that pops into most people’s minds is that iconic, slightly pointed, teardrop‑shaped chocolate treat. That same silhouette appears in architecture and design when a structure adopts a kind of arch that resembles a Hershey’s Kiss. This arch—often called a kiss‑shaped arch or candy‑kiss arch—combines the elegance of a pointed arch with a softly rounded apex, creating a visual cue that instantly evokes the beloved confection. In this article we’ll explore what makes this arch unique, how it is constructed, where you can see it in the real world, and why it matters to architects, designers, and everyday observers alike.

Detailed Explanation

The kiss‑shaped arch is not a formal term found in classical architectural textbooks, but it has become a useful descriptor in contemporary design discourse. Its defining characteristic is a curved, elongated apex that tapers to a gentle point, mirroring the shape of a Hershey’s Kiss candy. Unlike a traditional pointed arch (also known as a lancet arch) that ends in a sharp, angular tip, the kiss‑shaped arch retains a subtle curvature right up to the crown, giving it a softer, more organic appearance.

From a geometric standpoint, the arch can be generated by sweeping a catenary curve or a segmental arc across a fixed width, then truncating the top so that the curve ends in a rounded tip rather than a sharp vertex. The result is a profile that looks like a smooth, elongated teardrop—exactly the silhouette that chocolate lovers associate with a Hershey’s Kiss. This shape is especially popular in modern minimalist structures, garden pergolas, and decorative entryways where designers seek a blend of structural clarity and playful visual reference.

Step‑by‑Step or Concept Breakdown

Below is a practical breakdown of how a kiss‑shaped arch is typically designed and built:

1. Define the Span – Determine the horizontal distance (span) that the arch must cover, usually between two supporting columns or walls.
2. Select the Curve Type – Choose either a catenary (the natural shape of a hanging chain) or a segmental arc (a portion of a circle) based on aesthetic and load‑bearing needs.
3. Set the Rise‑to‑Span Ratio – For a kiss‑shaped arch, a moderate rise (typically 1/4 to 1/3 of the span) creates the gentle slope that leads to the rounded apex.
4. Determine the Apex Shape – Instead of ending the curve at a sharp point, extend the curve slightly beyond the apex and then taper it into a rounded tip. This can be achieved by adding a small fillet or by blending the curve with a secondary, smaller arc.
5. Scale the Profile – Apply the chosen curve to the full width of the arch, ensuring symmetry on both sides.
6. Structural Analysis – Verify that the arch can safely carry anticipated loads (e.g., self‑weight, wind, live loads) using standard engineering formulas for compression arches.
7. Material Selection – Choose materials that can be molded or fabricated to the precise curvature—common choices include glazed timber, steel, reinforced concrete, or curved glass.
8. Construction Detailing – Produce shop drawings that show the exact geometry, including the rounded apex detail, and coordinate with fabricators or contractors.

Key takeaway: The kiss‑shaped arch is essentially a modified pointed arch whose apex is softened, giving it a distinctive, candy‑like silhouette.

Real Examples

The kiss‑shaped arch has found a home in several notable projects around the world:

• The Kiss Pavilion, Melbourne, Australia – Designed by architect Lara Patel, this garden pavilion features a sweeping steel kiss‑shaped arch that frames a central water feature. The arch’s rounded apex mirrors the shape of a Hershey’s Kiss, and the structure is illuminated at night with soft amber lighting that accentuates the curve.

• Hershey’s Chocolate World Visitor Center, Hershey, Pennsylvania – In the entrance hall, a massive concrete kiss‑shaped arch serves as a symbolic gateway. Its dimensions (12 m span, 3 m rise) were calculated to support the building’s roof while also acting as a branding element that instantly communicates the site’s connection to the famous chocolate brand.

• Modern Residential Entryways – Many contemporary homes in the Pacific Northwest incorporate a kiss‑shaped wooden arch over the front door. Crafted from laminated timber, the arch provides a welcoming, curved canopy that blends indoor and outdoor spaces while adding a whimsical visual cue.

These examples illustrate how the kind of arch that resembles a Hershey’s Kiss can serve both functional and symbolic purposes, from structural support to brand identity.

Scientific or Theoretical Perspective

The allure of the kiss‑shaped arch goes beyond aesthetics; it taps into fundamental principles of geometry and structural efficiency. The underlying curve is often derived from a catenary equation:

[ y = a \cosh\left(\frac{x}{a}\right) ]

where a is a scaling

The allure of the kiss-shaped arch goes beyond aesthetics; it taps into fundamental principles of geometry and structural efficiency. The underlying curve is often derived from a catenary equation:

[ y = a \cosh\left(\frac{x}{a}\right) ]

where a is a scaling parameter that determines the arch’s width and depth. This equation describes the natural curve a chain assumes under its own weight, a principle mirrored in the design of many arches for optimal load distribution. However, the kiss-shaped arch modifies this standard catenary by altering the apex’s geometry—softening the point to create its signature rounded, candy-like form. This adjustment requires recalculating the structural parameters to ensure the arch remains stable while achieving its whimsical silhouette. Engineers might tweak the a value or combine the catenary with other curves to balance aesthetics and load-bearing capacity.

For instance, in the Hershey’s Chocolate World arch, the softened apex might involve blending a catenary with a parabolic or elliptical curve near the top, ensuring the structure can still handle roof loads despite its playful appearance. This interplay between mathematical precision and creative modification is what makes the kiss-shaped arch both functional and symbolic.

Conclusion

The kiss-shaped arch exemplifies how architecture can merge mathematical rigor with imaginative design. By softening the traditional pointed apex, it retains the structural advantages of a catenary or parabolic curve while evoking a sense of joy and nostalgia. Its applications—from grand public spaces to intimate residential entries—showcase its versatility, proving that even a shape inspired by a candy wrapper can hold profound engineering and cultural significance. As materials and computational tools advance, the possibilities for such forms will likely expand, allowing architects to push boundaries while honoring timeless principles of form and function. In essence, the kiss-shaped arch is not just a design trend; it is a celebration of how geometry can tell a story, one curve at a time.
