Hypothetical open‑market/insurance valuation for Claude Monet’s The Thames below Westminster (c. 1871): $45–70 million. The work is a museum‑caliber, early London subject that anticipates Monet’s famed 1899–1904 London cycle; it should price below the peak late‑series canvases but above most 1870s landscapes. As the picture is in the National Gallery, this figure serves as a replacement benchmark rather than a near‑term transaction estimate.

Overview and significance. The Thames below Westminster (c. 1871) is an important early London view painted during Monet’s first stay in the city. It captures the atmospheric effects along the Thames with Westminster in the distance and foreshadows the artist’s celebrated London cycle of 1899–1904. The painting has long resided at the National Gallery, London (bequeathed by Lord Astor of Hever in 1971), where the museum notes an incomplete 1933–45 provenance window; it is widely published and frequently displayed, underscoring its institutional stature [1]. At approximately 47 × 73 cm, its intimate format and silvery tonalities exemplify Monet’s early exploration of urban modernity and light.
Market benchmarks. Recent auction results establish the pricing envelope for Monet’s best cityscapes and late masterpieces. A prime Houses of Parliament from the mature London series brought $75.96 million at Christie’s in 2022 [2]. Waterloo Bridge canvases from the same cycle realized $48.45 million at Christie’s New York in 2021 and £30.06 million (≈$36.8 million) at Christie’s London in 2022 [3][4]. Beyond London, top Water Lilies achieved $74.01 million at Christie’s in 2023 and $65.5 million at Sotheby’s in 2024, confirming the depth of demand for Monet’s most coveted series [5][6]. Monet’s overall record remains $110.7 million for a Haystacks painting (2019), which frames the category’s apex [7].
Positioning this work. While the late London canvases (1899–1904) and Water Lilies command the very top of Monet’s market, an early, museum-caliber Westminster subject carries its own rarity and art-historical cachet. Relative to the mature London cycle, the 1871 date argues for a modest discount; however, the iconic subject (Westminster/Thames), strong early execution, and National Gallery pedigree narrow that gap. Recent outcomes across key series support a mid–eight-figure range: we calibrate $45–70 million as a prudent bracket, further underpinned by the $42.96 million Poplars record in 2025, which demonstrates sustained depth beyond the late London and Nymphéas peaks [10].
Practical considerations. There is no modern public auction for this specific canvas; it was sold via Arthur Tooth & Sons to J. J. Astor in 1936 and entered the National Gallery in 1971 [1]. Any deaccession is highly unlikely, so this valuation functions as an insurance/replacement proxy rather than a transactional forecast. Market conditions have grown more selective since 2024, with a trophy slowdown followed by a 2025 rebound led by historical categories; blue‑chip Impressionists like Monet continue to benefit from connoisseur-led demand and disciplined underwriting [9]. As with all Monets, condition, palette, and scale can move the needle within the stated band; a pristine state and notable exhibition literature would bias to the upper half of the range, while restorations or presentational issues would warrant the lower half.
Key Valuation Factors
Art Historical Significance
High ImpactPainted during Monet’s first London stay (1870–71), The Thames below Westminster captures the atmospheric effects that would become central to his later, market‑defining London series. It documents a pivotal turning point in his approach to urban light and fog, linking early Impressionist exploration to the serial practice of 1899–1904. The painting’s long residence and frequent display at the National Gallery, London, amplify its scholarly and cultural resonance. Within Monet’s oeuvre, it is best characterized as a major work of an earlier phase—arguably the genesis of a motif that later reached commercial and critical apogee. This pedigree strongly supports a trophy‑level valuation despite predating the mature London cycle.
Subject Rarity and Date
High ImpactEarly London subjects from 1871 are comparatively scarce in the market relative to the 1899–1904 London series. While the mature series is generally preferred commercially, the Westminster/Thames theme is globally recognized and institutionally coveted, attracting the same buyer pool that competes for Houses of Parliament and Waterloo Bridge. The 1871 date suggests a discount to the late series, yet the subject’s iconography and the work’s museum stature partially offset that. As a result, the picture can be credibly bracketed by mature London outcomes while acknowledging its earlier, less serial character. This rarity‑plus‑iconography mix supports mid‑eight‑figure pricing.
Comparable Market Performance
High ImpactRecent results anchor expectations: Houses of Parliament (1900–03) realized $75.96m (2022), while Waterloo Bridge canvases achieved $48.45m (2021) and £30.06m (≈$36.8m) in 2022. Prime Water Lilies have tested the $65–74m zone, and Monet’s overall record remains $110.7m. These outcomes evidence deep global demand for Monet’s top series and cityscapes, establishing an empirical range within which an early Westminster subject should logically calibrate. Given the painting’s earlier date, a pricing step‑down from late London is reasonable; still, subject quality and institutional pedigree justify a valuation materially above most 1870s landscapes. Net, the $45–70m band reflects current, quality‑selective market behavior.
Provenance, Ownership, and Feasibility
Medium ImpactThe painting’s chain includes Durand‑Ruel, Ernest Hoschedé, Jean‑Baptiste Faure, Arthur Tooth & Sons, and J. J. Astor, before entering the National Gallery in 1971. The museum flags an incomplete 1933–45 provenance window, typical of many European works of the era, but the picture has long been publicly held and widely exhibited. As a practical matter, deaccession is improbable; thus, the estimate functions as an insurance or replacement proxy rather than a near‑term sale forecast. Museum stature enhances desirability and narrative value, but the lack of transactional visibility for this exact canvas and the institutional context argue for a disciplined, comps‑led approach within a mid‑eight‑figure range.
Sale History
The Thames below Westminster has never been sold at public auction.
Claude Monet's Market
Claude Monet is a premier blue‑chip artist with a deep, global collector base and a multi‑decade record of liquidity at the highest end. His auction record stands at $110.7 million for a Haystacks painting (2019), and top series—including Water Lilies, late London views (Houses of Parliament, Waterloo Bridge), Poplars, Rouen Cathedral, and Venice—regularly achieve results from the mid‑eight to nine figures. Recent marquee sales have confirmed this resilience: Water Lilies canvases sold for $74.01 million (2023) and $65.5 million (2024), while a Poplars achieved $42.96 million in 2025. The market is selective and quality‑driven, rewarding strong provenance, condition, scale, and palette. Supply of A‑plus Monets remains scarce, sustaining pricing power when prime works appear.
Comparable Sales
Le Parlement, soleil couchant

Current Market Trends
High‑end auctions cooled in 2024, with fewer $10m+ lots and greater bidding discipline, but 2025 saw a rebound led by historical categories, including Impressionist and Modern. Demand is connoisseur‑driven and highly selective: canonical names with proven liquidity—like Monet—continue to perform, while guarantees and irrevocable bids help anchor trophy consignments. Macro conditions (tighter credit, higher financing costs) favor blue‑chip collateral over speculative names. Within this context, best‑in‑class Monets (Water Lilies, late London, Venice) still command premium multiples, and strong results in 2023–2025 reaffirm depth for iconic motifs. Expect continued estimate discipline, with quality, provenance, and condition determining whether works clear upper bands.
